	Title	Note Concerning Restricted Rotation about Metal-Acyl Carbon Bonds
	Abstract	A recent article by LINDNER et al. reported some interesting data on new alkyl and acyl cobalt tricarbo-nylphosphine complexes, RCo (CO) 3P<Z>3 , R = CHF2, CH2F, CHF2CO, CH2FCO x . Of particular interest were the infrared spectral data of the carbonyl region which indicated the expected pseudo Csv symmetry for all the complexes and in addition reported the ketonic carbonyl band for the monofluoroacyl complex to be a doublet, the relative intensities of whose bands were temperature dependent. Such behavior is typical of the existence of rotational isomers and was explained on this basis, namely restricted rotation about the metal-acyl bond. It was proposed that such restricted rotation stemmed from the double bond character of the linkage due to contribution of the well established limiting structure A to the acyl-metal bond.

	Title	Photoreaktionen von Dekacarbonyldirhenium mit A llen und unverzweigten Allenderivaten Photoreactions of Decacarbonyldirhenium with Allene and Unbranched Derivatives o f Allene
	Abstract	Decacarbonyldirhenium (1) reacts upon U V irradiation with allene (2), 1,2-butadiene (3) and 2,3-pentadiene (4) preferentially by CO substitution and oxidative rearrangement to the corresponding enneacarbonyl-//-?/1:3-endiyl-dirhenium complexes 5, 9, and 15 and to the octacarbonyl-,«-//-:2-allene-dirhenium complexes 6, the stereoisomers 10, 11, and 16. A t ele vated temperature 5, 9, and 15 loose CO and yield by a reductive rearrangement also the complexes 6, 10, 11, and 16. In addition to these main products, depending upon the allene derivative used, various by-products are obtained. By-products of the reaction o f 1 with 2 are octacarbonyl-M-/73:3-(2,3-dimethylene-buta-l,4-diyl)dirhenium (7) and ^-^^-allene-hexacarbonyl-/!-//1:3-i-propene-l,3-diyl-dirheniurn (8). The photo reaction of 1 with 3 yields, in addition to 9-11 , tetracarbonyl-^3-(£'-5-ethylidene-4-methyl-2-cyclopenten-l-yl)rhenium (12)

	Title	N NQR in 1,10-Phenanthroline and Dicyano bis(l,10-phenanthroline)iron(III)
	Abstract	14 N NQR spectra of 1,10-phenanthroline and of dicyano bis(l,10-phenanthroline)iron(lll) were obtained at room temperature. An analysis based on the shifts of the NQR frequencies and in the topology of the charge distribution in a model (pyridine) showed that the complex formation produces a strong decrease in the N valence shell nonbonded maximum and an increase in the bonded density along each of the N-H bond directions. The NQR spectrum showed that the complex formation produces only small changes in the charge distribution of the cyanide groups.

	Title	N NQR and the Molecular Charge Topology in Coordinated Ammonia
	Abstract	14 N NQR spectra of [Co(NH3)6] • 3C1, [Co(NH3)5C03] • N03, [Zn(NH3)4] • 2C1, [Zn(NH3)4] • (BF4)2, and [Ag(NH3)4] • N03 were obtained at 77 K. The results, analyzed by means of the topology of the charge distribution obtained from ab-initio MO calculations of free and of a model of coordinated NH3, showed that bonding to the metal-ion produces a strong decrease (Co^>Zn %Ag) in the N nonbonded density ("lone pair") and an increase in the bonded maxima found in the N-H bond direction of the N valence shell.

	Title	An NQR Study of Inclusion Compounds Formed Between Small Chlorine-containing Molecules and Ä/s(N-alkylimidazolidine-2-thione)Cu(I) Halide Complexes
	Abstract	Twenty-five inclusion complexes formed by fe(N-alkyiimidazolidine-2-thione)cuprous halides with the small, chlorine-containing guest molecules CC1 4 , CHC1 3 , CH 2 C1 2 , CH 3 CC1 3 or C 2 H 2 C1 2 , have been prepared. Their 63 Cu and 35 C1 NQR spectra have been measured over the temperature range 77-300 K. For the corresponding bromides the 79 Br and/or 81 Br spectra have also been investigated. The studies reveal the number and symmetry of different inclusion site. The onset of rapid reorientation of the guest molecules is indicated by the fading out of their NQR signals between 77 and 300 K, whereas the resonances from the host molecules usually persist throughout this temperature range. However, as evidenced by discontinuities in the temperature-dependence of the NQR frequencies of the hosts, sixteen of the complexes show one or more phase-changes in this temperature-range.

	Abstract	Primary and secondary aminoalkylphosphanes R2N -(C H 2)" ,-P H 2 (R 2 = Me2, «Bu2, C5H 10, C4H 80 , 2-(l-Methyl-2-pyrrolidinyl); m = 2, 3, 6, 10, 11; 1 -6) or [R2N -(C H 2)m]2PH (7, R2 = C5H 10; m = 2) are accessible by aminoalkylation of PH 3 with tö-chloroalkylamines R2N -(C H 2)m-C l in the superbasic medium DM SO/KOH (DM SO = dimethylsulfoxide). By selective N-quaternization of 1, 2, 4 -6 with RT (R ' = Me, C"H2" + 1; n = 6 -8 , 12, 16, 18) in the two-phase system CH2C12/H 20 novel primary phosphanes [R 'R 2N -(C H 2)m-P H 2]+I~ (ll-1 6 f) with quaternary ammonium groups in the alkyl side chain are obtained. The water solubility of l l -1 6 f decreases with increasing chain length (n) of R'. 11 (R = R' = Me; m = 2) shows a trans conformation at the C2H 4 bridge according to an X-ray structural analysis. Protonation of 1, 2, 4, 5 with HC1 affords the water-soluble hydrochlorides [HR2N -(C H 2)" ,-P H 2]+C1~ (19-22). The cationic primary phosphanes l l -1 6 f are stable towards oxygen. By oxidation of 11 with one or two equivalents of H 20 2 the primary phos phane oxide [Me3N -(C H 2)2-P (0) H 2]+I~ (23) or the phosphonous acid [Me3N -(C H 2)2-P (0)(0 H)H ]+I~ (23aj are formed. Hofmann degradation of 11 or 16c with KOH yields phosphirane in good yields. Reaction of 1, 2, 4 -6 (L) with Fe2(CO)9 at ambient temperature yields stable complexes (CO)4FeL (26-30). U nder more rigorous conditions Fe3 clusters (31, 32) with free R2N groups are obtained.

	Title	Formation of r71-P-(2-Phosphinophenol)Ni(0)(PMe3)3 and Oxidation to cjs/fraws-Bis(2-phosphinophenolato)nickel(II) Complexes
	Abstract	o-Phosphinophenols 1 (P ^ O H) react with equimolar amounts of Ni(PMe3)4 at low tempera tures to give yellow Ni(0) complexes such as [(HO~P)Ni(PMe3)3] 2a with only P coordination of the P ^ O H ligand. Oxidation of solutions of 1 and Ni(PMe3)4 by dioxygen leads to brown bis(o-phosphinophenolato-P^O)nickel chelate complexes 3a-d. Structure elucidation by NM R is consistent with a m-square planar geometry for 3a-c and a rrans-square planar solution struc ture of the terr-butylphenylphosphino derivative 3d. The geometric isomers were distinguished by different ranges of phosphorus coordination shifts and 3lP-l3C-2 and 3IP-13C-1 coupling

	Title	Cadmium-Isocitrate Complex: Its Stability as a Function of Ionic Strength
	Abstract	The complexation of cadmium by isocitrate has been studied at 25 °C and pH 7.5 in a range of ionic strength from 0.01 to 0 j16. The formation constant of the complex between cadmium and tribasic isocitrate varies from 860 M -1 at ^ = 0 .1 6 to approximately 24,500 M -1 at infinite dilu tion. These data allow the distribution of the chemical forms of cadmium added to the incubation mixtures for the assay of NAD-dependent isocitrate dehydrogenase to be calculated.

	Title	Phenylalanyl-tRNA Synthetase from Baker'Yeast: Structural Organization of the Enzyme and Its Complex with tRNAPhe as Determined by X-Ray Small-Angle Scattering
	Abstract	The quaternary structure of the phenylalanyl-tRNA synthetase and its complex with tRNAPhe was studied in dilute solutions by small angle X-ray scattering. For the free synthetase the radius of gyration was determ ined as 5.5 nm, the volume 523 nm 3, the maximum diam eter 17.5 nm and the m olecular weight as 260 000 using an isopotential specific volume of 0.735. The overall shape could be best approxim ated by a flat cylinder with dimensions 18.2 n m X l l .5 n m X 4 nm ; the loose structure was approxim ated by building up the cylinder by spheres (diam eter 4.2 n m). The corresponding param eters of the enzyme tRN A complex were the following: radius of gyration 5.9 nm, volume 543 nm 3, maximum diam eter 21 nm and m olecular weight 290 000. These param eters suggest an 1:1 complex, whereby it m ust be assumed that the tRN A m olecule is attached in the extension of the longer axis. From the difference in the distance distribution functions of the free enzyme and the complex it is evident that we have to assume a change of conform ation (contraction) of the enzyme upon the binding of the specific tRNA.

	Title	Ein neues Verfahren zur spektrometrischen Analyse von Metallkomplex-Lösungen A New Method for Spectrometric Analysis of Complex Metal Solutions
	Abstract	A new simple method is given to analyse potentiometrically titrated and spectrophoto-metrically measured complex-solutions of the system AH ^ A -j-H3Ü+ and n • A + M^MA n . The absorbance coefficients of the metal complex MA n and the stability constants can be determined for each titration step by construction of the "extinction triangle" in the (two-dimensional) absorbance (E) diagram. It is not necessary to know the absolute pH value of the solution. The titration of 2-nitroso-l-naphthol-4-sulfonic acid/zinc sulfate in water is shown as an example.

	Abstract	Bis(?j 5 -cyclopentadienyl)N,N-disubstituted Dithiocarbamato(chloro)oxomolybdenum(VI) complexes of the type (C5H5)2MoO(S2CNR2)C1 and (CsHshMoO^CNRR'JCl where R = Me, Et, «'-Pr and R' = cyclohexyl (cyhx) have been prepared by the reaction of stoichio- metric amounts of bis(^5-cyclopentadienyl)oxomolybdenum(VI) dichloride with sodium dichio-thiocarbamates in refluxing dichloromethane. Infrared spectral studies demonstrate that in these complexes, the dithiocarbamate ligands are bidentate. Hence a coordination number of 7 may be assigned to the molybdenum(VI) atom in each case. In addition to infrared studies, electronic spectra, NMR studies, magnetic susceptibility, elemental analyses and conductance measurements have been carried out for these complexes.

	Title	The Rieske Protein from Purple Sulfur Bacteria Is an Extrinsic Protein
	Abstract	The mode of membrane attachment of the Rieske iron-sulfur protein from cytochrome be, complex of Rhodospirillum rubrum has been studied using biochemical approaches. In contrast to cytochrome c, the bacterial Rieske protein was extracted from chromato-phores using chaotropic agents (NaSCN, urea, guanidine), an alkaline pH and relatively low concentration of Triton X-100.
