 Title    3-Triorganostannyl-N-diphenylmethylen-alaninestern Synthesis, Structure and Reactivity o f 3-Triorganostannyl-N-diphenylmethylene- alanine Esters  
 Abstract    The deprotonation of N-diphenylmethylene-glycine esters, obtained from glycine ester hy­ drochlorides and benzophenone imine, and reaction of the resulting carbanions with iodo-methyl triorganostannanes gives the 3-triorganostannyl-N-diphenylmethylene-alanine esters Me2RSnCH2CH(N=CPh2)COOR' (la -e\ R = Me, 'Bu; R' = Me, Et, 'Bu, Bz). These title compounds are transformed into their tin monochlorides MeR(Cl)SnCH2CH(N=CPh2)COOR' (2a -e) by a redistribution reaction with Me2SnCl2. IR and NMR data and the crystal structure of Me2(Cl)SnCH2CH(N=CPh2)COOEt (2b) reveal for 2a -e an intramolecular coordination of the ester C = 0 group at the tin atom. Mild two-phase hydrolysis of la -e with IN HC1 gives the 3-triorganostannyl-alanine ester hydrochlorides Me2RSnCH2CH(NH 2)COOR' • HC1 (3a -e). The transformation of 3a -e into the corresponding alanine esters Me2RSnCH2CH (N H 2)COOR' (4a -e) could be realized with NH3 in chloroform. 4a -e are of limited thermal stability.

 Abstract    2.4.6-Tri-f£T/-butylphenyl Group. Aminofluorosilane, Lithium-fluorosilylamide, 1,3-Siloxane, Tris(fluorosilyl)amine 2,4,6-Tri-ter/-butylphenyltrifluorosilane (1) reacts with lithium amides to give the aminofluo-rosilanes (2 -7); RSiF2NHR' (R = 2,4,6-Me3CC6H 2; R' = H (2), CM e3 (3), SiMe2CM e3 (4)), (R-SiF2)2NH (5), RSiF(NHR')2. R' = CM e3 (6), C6H5 (7). The reaction of 5 with BuLi in THF leads to the formation of the monomeric lithium derivative 8, R-SiF2Li®(THF)3-N " -SiF2R. The polymeric lithium derivative 9 [R-SiF2-N H -SiRF2L i*(T H F)2]" is obtained by recrystallisation of 8 in THF. In 8 and 9 lithium is only coordinated to fluorine and THF. Hydrolysis of 8 or 9 lead to the 1,3-disiloxane 10, (RSiF2)20 . 10 shows linearity at the oxygen and short S i-0 bond lengths.

Crystal Structures o f a Free Ligand and o f Nickel(II), Copper(II) and Zinc(II) Complexes  
 Abstract    The syntheses and structural characterizations of complexes of two 14-membered macrocy­ clic trans-N4 dibenzo ligands, 5,7,8,9,14,16,17,18-octahydrodibenzo[e,l]-[l,4,8,l ll-tetraaza-cyclotetradecine-6,15-dimethyl (L3) resp. -6,15-diacetamide (L4), are presented. The crystal structures of five compounds have been determined by single crystal X-ray diffraction. The free ligand L3 has a saddle-shaped structure with intramolecular hydrogen bonds. This conformation of the ligand exists also in the Zn(II) complex in which the metal ion is five-coordinated with the metal center outside the cavity. The coordination polyhedron is intermediate between a trigonal bipyramid and a square pyramid. In c/5-[Ni(L3)(NCS)2] the ligand is folded along an N- • N axis. The nickel ion in this complex shows an approximate octahedral geometry. For Ni(II) and Cu(II) complexes of ligand L the overall geometry is also distorted octahedral. The folding of the ligand causes a d s-N 40 2 coordination.

 Title    Metallkomplexe mit 2,2'-Dipyridylamin als Liganden: Kristallstrukturen der Komplexe mit CdX2 (X = Cl, Br, I) und CuCN Metal Complexes with 2,2'-Dipyridylamine as Ligand: Crystal Structures o f the Com plexes with CdX2 (X = Cl, Br, I) and CuCN  
 Abstract    Reactions of 2,2'-dipyridylamine (dpyam) with cadmium halides yield crystals of [Cd(dpyam)(H20)C l2] (1), [Cd(dpyam)Br2] (2), and [Cd(dpyam)I2] (3). With CuCl2 and KCN a complex [C u(dpyam)C N ]H 20 (4) is obtained. Depending on the size of the halide ions the coordination changes from octahedral in 1 to trigonal bipyramidal in 2 and tetrahedral in 3. The coordination in 4 is trigonal. Due to the geometric strain imposed by the ligand all coordination polyhedra show significant distortions. 1 and 2 form dimers by halide bridges. With the excep­ tion of 3 all compounds form "supramolecular" structures via hydrogen bonds, e.g. chains or networks.

 Title    Copper Complexes with the Ligand [Cp2MoH2]  
 Abstract    The reaction of CuCl with [CP2M0H2] yields the complex [Cu(Cp2M oH2)2Cl]. An X-ray structure analysis shows that the coordination of the copper(I) ion by two [CP2M0H2] lig­ ands and the chloride ion is pseudo-trigonal planar. The hydride ligands were located by using difference Fourier methods. A manifold of reactions took place when an aqueous so­ lution of CUSO4 was treated with a solution of [Cp2M oH 2] in dichloromethane in a 1:2 molar ratio. The X-ray structure analysis established a polymeric structure of the complex [Cu(Cp2MoH2)2Cu(Cp2M oH2)S0 4 ]" with two different copper centers.

 Title    Synthesis and Spectroscopic Properties of 1,2-Diiminetricarbonyl- rhenium(I)chloride Complexes with Aliphatic Diimines (or 1,4-Diaza-l,3-butadienes) as Ligands  
 Abstract    Re(l,2-diimine)(CO)3Cl complexes with the aliphatic bidentate ligands diiminosuccino-dinitrile (DISN), benzilbisanile (BEAN), bisacetylbisanile (BABA), and benzildiimine (BE­ DIM) are reported. The compounds show Re(I) to 7r*(diimine) metal-to-ligand charge transfer (MLCT) absorptions in the visible spectral region. The energy of these MLCT-transitions de­ creases in the series BABA > BEDIM > BEAN > DISN, depending on the 7r* acceptor properties of the coordinated diimine ligands. The maxima of these CT bands undergo a solvent-dependent shift (negative solvatochromism), which indicates a partial charge redistribution in the excited state. The compounds are not photoluminescent at room temperature and 77 K.

 Abstract    u-bis-(?7?-Hexahydro-c/0sohexaborato)bis(triphenylphosphine)digold, Polymorphism, Crystal Structure The crystal structure of a second room-temperature polymorph of the complex [Au2(/i-bis-r^-BftHöKPPhih] is presented and compared with the previously reported phase. The change of the solvent which is layered on a solution of [Aui^-bis-r^-BöHöXPPh.^] in CH2CI2 from petroleum ether to n-pentane leads to a second form with fundamental differences in the crystal structure. Instead of the octahedrally shaped crystals, space group Pa 3, the crystals in the present determination are orthorhombic needles crystallizing in space group Pccn with a remarkable increased calculated density from 1.326 to 1.855 Mg/m3.

Based on the molecular parameters of the X-ray determinations the low temperature (10 K) IR and Raman spectra of the (rc-Bu4N) salts have been assigned by normal coordinate analysis. The valence force constants are fd(ReN) = 1.68 and fd(ReSe) =1.15 mdyn/A.

 Title    Synthesis, Structure and Reactivity of 2-Amino-and 2-Imino-2,3-dihydro-1H -1,3,2-diazaboroles  
 Abstract    The 2-halo-2,3-dihydro-1H-1,3,2-diazaboroles RN-CH=CH-N(R)BX (la': R = rBu, X = Br; lb: R = 2,6-Me2C6H.v, X = I) were converted into the 2-amino-2,3-dihydro-\H -1,3,2-diazaboroles RN-CH=CH-N(R)B-NH2 (2a: R = /Bu; 2b: 2,6-Me2C6H3) by treatment with dry gaseous ammonia. Similarly reaction of la' with 2,6-dimethylaniline or /BuNHt afforded the corresponding derivates /BuN-CH=CH-N(rBu)BNHR' (3; R 1 = 2,6-Me2C6H3; 4; R1 = rBu). The treatment of la' with the ethylene diamine adduct of lithium acetylide led to the formation of [rBuN-CH=CH-N(/Bu)BN(H)CH2]2 (5). Lithiation of 2 a and subsequent silylation gave 6 (R1 = SiMe3), which was transformed to the diborolylamine [/BuN-CH=CH-N(rBu)B]2NH (7) upon exposure to la'. Borolylketimine /BuN-CH=CH-N(/Bu)B-N=CPh2 (8) and borolylcar-bodiimide fBuN-CH=CHN(/Bu)B-N=C=N-SiMe3 (9) resulted from la' and Ph2C=NSiMe3 or Me3SiN=C=NSiMe3, respectively. All the new compounds were characterized by elemental analyses as well as spectroscopic data (IR, 'H, n B, i3C NMR, MS). Heterocycle 5 was also subjected to an X-ray diffraction analysis.

 Abstract    Tetramethylammonium cyanide crystallizes in the tetragonal space group P4/nmm, Z = 2, with cell dimensions a = 773.6(1), c = 546.8(1) pm. The cyanide ion is disordered in the plane perpendicular to the c-axis indicating a rotation. The room temperature phase undergoes a thermal phase transition at -59.9°C probably caused by an order-disorder transition of the cyanide ion.

 Abstract    The photolysis of Cr(CO)6 and Ph3PAuN3 (1:2) in thf yields the unstable cluster cation [(Ph3PAu)5Cr(CO)4]+ that slowly decomposes to form the new homometallic gold cluster [Au(AuNCO)(AuPPh3)8]Cl. The cluster compound crystallizes in form of red needles in the tetragonal space group 14 with a = 2214.1(3), c = 1408.9(2) pm, and Z = 2. The inner skeleton of the cluster with the symmetry C4 consists of a centered square antiprism of nine Au atoms with the square faces of the antiprism being bridged by the AuNCO group, and a C P anion, respectively. The shortest Au-Au distances exist between the central and the 8+1 peripheral Au atoms ranging between 263.5(1) and 270.6(3) pm, the four Au-Cl distances are 280(1) pm.
