 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.
