 Title    Amidinatokomplexe von Bor, Aluminium, Gallium, Indium und Zinn Die Kristallstrukturen von Ph-C(NSiMe 3 ) 2 AICI 2 und Ph-C(NSiMe 3 ) 2 SnCl 3 Amidinato Complexes of Boron, Aluminium, Gallium, Indium, and Tin The Crystal Structures of Ph-C(NSiMe 3 ) 2 AlCl 2 and Ph-C(NSiMe 3 ) 2 SnCl 3  
 Abstract    The trichlorides of aluminium, gallium, and indium, as well as boron tribromide and tin tetra-chloride react with N,N,N'-tris(trimethylsilyl)benzamidine to form the monomeric N.N'-bis-(trimethylsilyl)benzamidinato complexes Ph-C(NSiMe,) 2 MX 2 (M = B, Al. Ga, In; X = Cl, Br) and Ph —C(NSiMe 3) 2 SnCl 3 , respectively. All compounds have been characterized by their IR spectra, two of them by X-ray diffraction studies. Ph — C(NSiMei) 2 AlCl 2 : Space group C2/c, Z = 4, 1152 independent observed reflexions, R = 0.052. Lattice dimensions (19 °C): a = 1558.6(1), b = 1116.6(1), c = 1307.0(1) pm, ß = 115.17(1)°. The compound forms monomeric molecules, in which the aluminium atom is tetra-hedrally coordinated by two chlorine atoms and by the two nitrogen atoms of the benzamidinato chelate. Bond length A1N = 188.2 pm. Ph — C(NSiMe^) 2 SnCU: Space group PI, Z = 2, 3293 independent observed reflexions, R = 0.034. Lattice dimensions (19 °C): a = 980.1(1), b = 1025.9(1), c = 1230.5(2) pm. a = 68.40(1)°, ß = 87.71(1)°, y — 68.92(1)°. The compound forms monomeric molecules, in which the tin atom is five-coordinated by three chlorine atoms and by the two nitrogen atoms of the benzamidinato chelate. Bond lengths SnN = 213.5 and 215.2 pm.

 Title    Kupfer(I)-chlorid-Addukte von Phosphoraniminen Die Kristallstrukturen von Ph 3 PNPh * CuCl und von 2,3-Bis(triphenylphosphoranylidenamino)maIeinsäure-N-methylimid- Kupfer(I)-chlorid Copper(I) Chloride Adducts of Phosphoranimines The Crystal Structures of Ph 3 PNPh-CuCl and of 2,3-Bis(triphenylphosphoranylideneamino)maleic Acid N-Methylimide Copper(I) Chloride  
 Abstract    The title compounds Ph,PNPhCuCl (1) and (Ph,P) 2 N : C 4 0 2 (NMe) CuCl (2) have been prepared by the reactions of CuCl with the corresponding phosphoranimines Ph 3 PNPh and 2.3-bis(triphenylphosphoranylideneamino)maleic acid N-methylimide, respectively. Both com-plexes were characterized by their IR spectra as well as by crystal structure determinations. PhiPNPh • CuCl (1): space group PI, Z = 4, 3639 independent observed reflexions, R = 0.038. Lattice dimensions (18 °C): a = 1047.6; b = 1251.5; c = 1755 pm; a = 103.43°; ß = 97.24°; y = 101.30°. The compound forms monomeric molecules; the asymmetric unit contains two crystallo-graphically independent molecules. The CuCl molecule is bonded via the N atom of the phos-phoranimine. Bond lengths: Cu—N = 189 pm; Cu —CI = 209 pm; bond angle N —Cu —CI = 177°. (PhiP),NiC 4 Oi(NMe) CuCl (2): space group Pbca, Z = 8, 5611 independent, observed reflex-ions, R = 0.069. Lattice dimensions (25 °C): a = 1224.3; b = 1962.5: c = 2994.0 pm. The compound forms monomeric molecules with the CuCl molecule bonded via one of the N atoms of the phosphoranimine groups. Bond lengths: Cu—N = 194 pm; Cu—CI = 212 pm; bond angle N—Cu —CI -175°.
