 Title    Synthese und Struktur von 2-Imino-l,3-dimethylimidazolin [1] Synthesis and Structure of 2-Imino-l,3-dimethylimidazoline [1]  
 Abstract    Deprotonation of the 2-amino-1,3-dimethylimidazolium salt 5 (obtained through methyla-tion of 2-am ino-l-m ethylim idazole (4)) by KH gives 2-im ino-l,3-dim ethylim idazoline 6. The trimethylsilylimino compound 14 is formed on the reaction of 6 with chlorotrimethylsilane in the ratio 2:1. Further reaction with chlorotrimethylsilane gives the silylated aminoimidazo-lium salt 15. The X-ray structures o f 5 and 6 are reported.

The radial distribution function revealed three distinct peaks assigned to the oxygen, amido carbon (CJ, and nitrogen atoms of six planar DMF molecules in the first coordination sphere around the metal atom. The distance from the cobalt atom to each atom (O, Cx, N) is 213,299, and 423 pm, respectively. This indicates that the Co-O-Cj bond angle is 122-123° and the metal atom is close to the O-Cj-N plane of the DMF molecule.

 Title    Triferrocenylborane -Molecular Structure in Solution and in the Solid State  
 Abstract    According to a single crystal X-ray structure determination all three ferrocenyl substituents of triferrocenylborane (1) adopt the same orientation with respect to the BC3-plane [P 2 Jc\ monoclinic; Z = 4; a = 1353.5(3), b = 1695.6(3), c = 1056.4(2) pm, ß = 109.27(3)°]. The simu­ lated X-ray powder pattern of the single crystal is identical with the powder diagram o f a macroscopic sample, indicating the presence of a single diastereomer (l a) in the solid state. How ever, at low temperature (< -9 5 °C) in solution, the 13C NM R spectra suggest the pres­ ence of the second diastereomer (lb) in which one ferrocenyl group is oriented opposite to the other two with respect to the central BC3-plane.

 Title    Synthesis, Structure, and Properties of Homoleptic l-Oxa-l,3-diene Molybdenum and Tungsten Complexes  
 Abstract    Homoleptic tris(l-oxa-l,3-diene)m olybdenum and tungsten complexes are formed as yel­ low, crystalline compounds in 54-80% isolated yield on treatm ent of the corresponding /3-unsubstituted a,/3-unsaturated ketones with W (CO)3(CH 3CH 2CN)3 or (y6-C6H 6)M o(CO)3 in refluxing hexane. Reaction of these oxadienes with (^6-C6H 5CH3)2Mo in tetrahydrofuran or /7-hexane provides a new high yield route to homoleptic molybdenum complexes that are otherwise difficult to prepare. X-ray crystal structure analyses of two air-stable, isomeric tungsten complexes reveal a significant contribution of a cr2,?/2-bonding mode in the coordi­ nated oxadiene moieties. U nder reaction conditions that allow the platinum catalyzed hydro­ genation of phenyl substituents in these ligands, the coordinated oxadiene fragments are inert, thus demonstrating an unprecedented chemoselectivity in the hydrogenation of aryl-substituted enones. On the other hand, the complexes are labile enough to catalyze the cyclotrimerization of alkynes such as methyl propiolate.

 Title    T h e R eaction o f D ien es with [F e (P r z2P ( C H 2) /IP P r /2) ] Species  
 Abstract    D ed ica ted to Prof. D r. Dr. h.c. m u lt G ü n th e r W ilk e o n the o cca sio n o f his 70th birthday The structure of the compounds formed upon reacting Fe(Pr'2P(C H 2)"PPr'2)Cl2 (n = 1-3) and active-Mg with acyclic and cyclic 1,3-, 1,4-and 1,5-dienes depends upon the nature of the diene and upon the length of the methylene-chain bridging the two P-atoms of the biden-tate ligand. For example, isoprene reacts to give either (774-isoprene)2FePPr'2C2H4PPr'2 or (^4-isoprene)Fe(Pr'2PC3H6PPr'2) while the products of the reaction with 1,5-hexadiene are (?75-l-methylpentadienyl)Fe(Pr'2PC2H 4PPr'2)H or (//2,?/2-l,5-hexadiene)Fe(Pr'2PC3H6PPr'2). The crystal structures of the last two compounds have been established by X-ray diffraction. The penultimate species catalyses the linear dimerization of 1,5-hexadiene.

 Title    EuPdGe -a New Germanide with EuNiGe Type Structure  
 Abstract    The title compound was prepared from the elem ental com ponents in a tantalum tube at 1070 K and investigated by X-ray diffraction of both powder as well as single crystals. The crystal structure was refined from four-circle diffractometer data: P 2 xln, a = 618.1(1), b = 613.6(1), c = 743.9(1) pm, ß = 109.40(1)°, V = 0.2661(1) nm3, Z = 4 ,w R 2 = 0.0536 for 1564 F2 values and 29 variables. EuPdGe crystallizes with the E uN iG e type structure. Both Pd and G e atom s in EuPdGe have three germanium or palladium neighbors, respectively. They form two-dim ensionally infinite [PdGe] polyanions which consist o f corrugated 4.82 nets. These polyanions are separated by the europium atoms.

 Title    Offene und geschlossene Triferriophosphonium-Salze und Triferriophosphane O pen and Closed Triferriophosphonium Salts and Triferriophosphines  
 Abstract    The reaction of P(SiM e3)3 with an excess of C pFe(CO)2X (X = Cl, Br) through the action o f water gives the triferriophosphonium salt [{CpFe(CO)2}3PH]2FeX4 together with ferrocene as by-product. The cation of the salt can be deprotonated by D B U to afford the unstable triferriophosphine {CpFe(CO)2}3P. Its subsequent realkylation with RX (R = Me, CH2Ph; X = I, Br) leads to alkyltriferriophosphonium salts [{CpFe(CO)2}3PR]X. Photolysis of [{CpFe(CO)2}3PH]2FeX 4 induces the elimination of one CO group, and the CO-bridged and partly closed complex [{//-CO(CpFeCO)2}{CpFe(CO)2}PH]2FeX 4 is formed, the cation of which can also be deprotonated to give the corresponding m onobridged phosphine (w-CO(CpFeCO)2}{CpFe(CO)2}P. Both PH-phosphonium salts undergo a hydrogen-chlorine exchange reaction to give the P -C l analogues [{CpFe(CO)2}3PCl]2FeX4 and [{//-CO (CpFeCO)2}{CpFe(CO)2}PCl]2FeX 4. The IR and NM R spectra of all species as well as the X-ray structure analyses of the open and closed P -H functional com plexes are reported and discussed.

 Title    Heteronuclear Nucleobase Complexes as Tools for the Isolation of the Minor Rotamer of the Parent Compound: Synthesis and Crystal Structure Determination of H ead-H ead and H ead-Tail Forms of rrfl«5-[(CH3NH2)2Pt(l-MeC-Ar J)2]2+ (1-MeC = 1-methylcytosine)  
 Abstract    The two rotamers (head-tail, 1, and head-head, 2) of the bis(l-m ethylcytosine)com plex of f/ww-(CH3N H 2)2Pt(II), have been crystallized as C104-(1, 2a) and PF6-(2b) salts and characterized by X-ray crystal structure analysis and 'H and 19:iPt NMR spectroscopy. In aqueous solution, 1 is preferred over 2 by 70:30. Upon slow crystallization from H 2Ö, 1 is obtained as the only product. Isolation of 2a and 2b has now been accomplished via forma­ tion of the heteronuclear derivative rrans-[(CH3N H 2)2Pt(l-MeCv/V3,./W)2Hg]2+, in which the deprotonated 1-methylcytosinato ligands (1 -M eC) are oriented head-head, precipitation of Hg(II) by thiourea, and rapid crystallization of the parent compound. The solid state struc­ tures of 1 and 2b differ markedly in a number o f aspects. Isolation of pure 1 and 2 permits a detailed study of the kinetics and thermodynamics of the interconversion of the two rotam­ ers. From comparison with the behavior of 1 and 2 in H20 on the one hand and DM SO and DM F on the other a clear solvent effect on the rotamer distribution is seen which most likely relates to differences in H bonding between solvent and solute.

 Title    Synthese und Kristallstrukturen von Diazadien-Komplexen der Erdalkalimetalle Syntheses and Crystal Structures of Diazadiene Complexes of the Alkaline Earth Metals  
 Abstract    [C aN R -CPh=CPh-N R (D M E)2] 1 (R = C6H4-4 -C H 3; D M E = dim ethoxyethane) was pre­ pared by reaction of calcium with N R = C P h -C P h = N R in D M E solution. The compound forms orange, moisture sensitive crystals, which were characterized by an X-ray structure determination [space group orthorhombic, P 2 i2 12 1, Z = 4, 4634 observed unique reflections, R = 0.046; lattice dimensions at -7 0 °C: a = 1340.2(3), b = 1528.1(3), c = 1609.1(3) pm]. The calcium atom is coordinated by the four oxygen atoms of two chelating D M E molecules and two nitrogen atoms of the diazadiene ligand, bonded in its enediam ide form. [Ba2(D M E)3(N P h -C P h = C P h -N P h)2 DM E] 3 was obtained from barium metal and N Ph=C Ph-C Ph=N Ph in D M E solution as red crystals [space group monoclinic, P2!/c, Z = 4, 4000 observed unique reflections, R = 0.166; lattice dim ensions at -7 0 °C: a = 1704.5(3), b = 1786.1(4), c = 2177.4(4) pm, ß = 105.98(3)°]. The two barium atoms are bridged by two differently bonded diazadiene ligands (/<2-N ,N ';/i-N ,a -N '). Additionally, one of the barium atoms is coordinated to two DM E m olecules and the other one to only one of the ether molecules. A further DM E molecule is a constituent of the crystal lattice.

 Title    2-Stannylpyridine-Borane Adducts -Multinuclear Magnetic Resonance Study and X-Ray Structure Determination of a l,4-Dihydro-4 a,l,4-azastannabora-naphthalene Derivative  
 Abstract    The adduct formation between 2-trimethylstannyl-pyridine (1) and triethylborane, leading to 2a, and 9-borabicyclo[3.3.1]nonane, leading to 2b, was studied by 'H, " B, 13C, 15N and 119Sn NMR in solution. Changes in the magnitude of the coupling constants 7(119Sn, 13C), with respect to the data for 1, were analysed. The absolute signs have been determined [all coupling constants " /(119Sn,13C) to methyl and pyridine carbon atoms in 1 to 3 possess a negative sign and the same is true for "y(119Sn,*H) of the pyridine hydrogen atoms] by various two-dimensional NMR experiments, and attributed to the influence of the lone pair of electrons at the nitrogen atom in 1. The NMR spectroscopic results for the 1,4-dihydro-4a,l,4-azastannabora-naphthalene derivative 3, in which structural fragments are present analogous to those in the borane adducts 2, correspond to those for 1 and 2a,b. The molecu­ lar structure of 3 has been determined by X-ray analysis [orthor' nombic; P 2 i2121; a = 713.9(2), b = 1566.0(2), c -1578.4(2) pm]. Solid-state 13C and 119Sn CP/MAS NM R spectra prove that the molecular structures of 3 in the solid state and in solution are very similar.
