 Title    Spectral and Thermal Studies on Some New Anionic Mixed Alkyldithiocarbonato-Oxinato Transition Metal Complexes  
 Abstract    A lkyldithiocarbonates, Transition M etal C om plexes The preparation and characterization o f som e anionic mixed ligand com plexes o f C o(II), N i(II) and C u(II) containing the two anionic ligands alkyldithiocarbonate and oxinate are reported. The ionic nature o f the com plexes was inferred from the conductivity data. Alkyldithiocarbonates act in these com plexes as bidentate ligands. Based on the spectroscopic and m agnetic data the com plexes appear to possess pseudo-octahedral metal coordination.

 Abstract    l,3^~Tris(dimethylamino)benzol und l,2,3?4,5,6-Hexacyanobenzol Donor/Acceptor Complexes from l,3,5-Tris(dimethylamino)benzene with 1,2,3,4,5,6-Hexacyanobenzene M agnetism , Highly Symmetrical D on or A cceptor C om plexes Reaction o f l,3,5-tris(dim ethylam ino)benzene (T D M A B) with 1,2,3,4,5,6-hexacyanobenzene (H C N B) in acetonitrile solution gives -depending on the crystallization m ethod -two different products: dark needles o f a 1:1 (1) and black compact crystals with a m etallic lustre o f a 2:1 (2) charge transfer com plex. 2 crystallizes in the triclinic space group P I , Z = 1, a = 9.9489(22), b = 10.0555(21), c = 10.1418(20) Ä , a = 115.006(16)°, ß = 102.820(17)°, y = 93.647(18)°, V = 882.3 Ä 3, dc = 1.2 gcm ^ 3, measured at room tem perature, R = 0.053 for 2670 observed independent reflections and 301 parameters. The structure contains isolated "trim ers" o f one H C N B acceptor which is "pancaked" by two T D M A B neighbors. The arrangement o f these trimers in the lattice results in alternating H CNB and T D M A B sheets. The solid is diam agnetic. 1 could not be obtained in crystals suitable for a single crystal X-ray investigation. Its para­ m agnetism which is observed im m ediately after preparation disappears in the course o f several days.

 Title    Strukturuntersuchungen an chiralen Schiff-Basen des 11-c/s-Retinals Structure Investigation of Chiral Schiff Bases of 11-m-Retinal  
 Abstract    Retinals, Schiff Bases, Chirality CD and U V spectra o f four chiral 11-m -retinal Schiff bases obtained by condensing the aldehyde with asymmetric amines are used to gain structural information about the polyene conformation. The spectra are tem perature-dependent indicating the same 12-s-cis/trans equilibrium as in 1 l-c/5-retinal. In addition, CD absorptions arise at lower temperatures whose only origin is the inherent dissymmetric nature o f the retinylidene Chromophore. C N D O /S-calculations performed on the basis o f force-field optim ized geom etries give results which can partially be rationalized on the basis o f experimental data. Q uantitative agreement bonded dimers.

 Title    Die absolute Konfiguration der Juglomycine The Absolute Configuration of the Juglomycins  
 Abstract    A ntibiotics, Juglom ycins, A bsolute Configuration, NMR D ata, Derivatives The absolute configurations of the known juglomycins A (1) and B (2) have been elucidated by single crystal X-ray structure analysis o f 1 and its 6,8-dibromo derivative (l b) . The structure o f 2 has been corrected; it differs from 1 in its configuration at C -4', and not at C-3' as previously assum ed. R elationships with the closely related isochromanquinone antibiotics are discussed.

 Title    Regular Octahedral Coordination of As(III) in the Anion [As3Br12]3_ Structural Correlation of the Antibonding Influence of the As 4s-Orbital in Bromoarsenates(III)  
 Abstract    Brom oarsenates(III), X -R ay, Structural Correlation. B ond Valences The b rom oarsen ates(lll) [Et4N ]3[A s3B rl2] (1). [Ph4P]2[A s2Brs] (2), [(/z-prop)4N]2[A s2Brs] (3) and {[pipH ]3[A s2Bn,] • [pipH]Br} (4) have been prepared and their structures established by X-ray structural analysis. The central A s atom in the novel face-bridged trioctahedral species [A s;Br,2] displays an effectively regular octahedral coordination in one o f the two independent anions in the unit cell o f 1. The A s —Br distances are 2.671 (1) — 2.672(2) Ä with Br—A s —Br angles in the range 88.8(1)—91.2(1)°. In contrast the outer A s atom s exhibit a severely distorted octahedral geometry with three short A s -B r terminal bonds (2 .4 0 4 (2)—2.409(2) Ä). The [A s:Br,s]2 anions in 2 and 3 are centrosym metric with the A s atom s displaying a square-pyramidal coordination. A structural correlation o f opposite A s —Br distances in the linear three-centre B r—A s -Br interactions is presented. The sum of the bond valences in brom oarsenates(III) is a minimum for the regular octahedral geom etry, reflecting, thereby, the influence o f the As 4s-orbital in the antibonding 2 a lg MO. An empirical expression for A s —Br distances in brom oarsenates(III) is derived.

Cycloaddition. X-Ray R eactions of the low valent azido complex N Et4[CpM n(CO)2N3] (1) with electrophiles prefer­ ably give the dinitrogen complex [CpM n(CO)2N2] (2). Thus, 2 forms when 1 is reacted with N O B F4, N 0 2BF4 or HC1/THF. respectively. 2 forms also if 1 is reacted with the 1,3-dipolarophile CI3 C —CN. The reaction of 1 with C H ,I. however, gives the methylam ine complex [C pM n(C O)2N H 2CH 3], presumably via methylazido, -nitrene and -aminyl interm ediates. Cyclo-additions could be achieved with the isoelectronic [CpFe(cdpe)N,] (3); 3 yields the corresponding 2-triazolato-4,5-dialkylester complexes 4 when reacted with R 0 2C —C = C —C O ; R (4a: R = Me; 4b: R = E t). The ethyl derivative was characterized by X-ray structure analysis.

 Title    Neuartige basische Liganden für die homogenkatalytische Methanolcarbonylierung, XXI [1] Synthese und Eigenschaften von (Ether-Phosphan)-Platin-Komplexen Novel Basic Ligands for the Homogenous Catalytic Methanol Carbonylation, XXI [1] Synthesis and Properties of (Ether-Phosphane) Platinum Complexes  
 Abstract    The (ether-phosphane) complexes m -C l2Pt(Ph: P ~ D)2 (2a, b) [D = C H 2C4H 70 (a). C H 2C4H 70 2 (b)] are obtained by reaction of Ph2P ~ D (la , b) with either K2PtCl4 or Cl2Pt(CO D) (C O D = 1,5-cyclooctadiene). Both Cl ^anions are abstracted from 2a, b using A gSbF(1 to give the cationic bischelate complexes [Pt(Ph2P D)2][SbFh]2 (5a, b). The stepwise cleavage and reform a­ tion of Pt —O bonds in (ether-phosphane) platinum complexes is dem onstrated bv the sequence 5a —> [rä -(P h 2P D)(Ph2P ~D)P tC l][S bF 6] (6 a) -* [rra«5-(Ph2P ~ D)2PtC O (C l)][SbF6] (7 a) -* 5a, when 5a, 6 a, and 7a are reacted with KC1. CO, and AgSbF,,, respectively. Reduction of 2a with N aB H 4 results in the form ation of rra/2s-H 2Pt(Ph2P ~ D)2 (4a). In the presence of HC1 2a js re­ formed. Excess N aBH 4 or heating of 4a yields the bischelate platinum(O) complex Pt(P h: P D)2 (3a), which is also jso lated by reduction of 2a with sodium amalgam. A general method for obtaining P t(P h2P D)2 (3 a —c) [D = C H 2C H 2O C H , (c)] is the substitution of C O D in P t(C O D)2 by the ether-phosphanes l a —c. The structures and bonding properties of the com pounds 2 —7 are discussed on the basis of their 31P {1H } NMR and IR spectra.
