Crystal Structures of [ZnCl2(M e3SiNP(CH2)4CM e3)]2, [ZnI2(Me3SiNPEt3)]?, [Znl2{Me2Si(NPEt3)2}], and [ZnBr(NPMe3)]4 CH2Cl2 The donor-acceptor complexes [ZnCl2(Me3SiNP(CH2)4CMe3)]2 (l)and [ZnI2(Me3SiNPEt3)]2 (2) have been prepared from the zinc dihalides and the corresponding silylated phosphaneimi-nes in CH2C12. Thermolysis of 2 leads to the formation of [ZnI2(Me2Si(NPEt3)2)] (3). Znl2 and ZnBr2 react with the silylated phosphaneimines Me3SiNPR3 (R = Me, Et) in the presence

 Title    [TiJv Cl8(NPMe3)3]Cl und [Vnw vCl4(NPPh3)3] Crystal Structures of the Phosphoraneiminato Complexes [Ti3v Cl8(NPMe3)3]Cl and [vl"/IVCl4(NPPh3)3]  
 Abstract    [Ti3Cl8(NPMe3)3]Cl has been prepared by the reaction of TiCl3(THF)3 with Me3SiNPMe3 in dichloromethane forming green moisture sensitive crystals. According to the crystal structure determination the titanium atoms of the cation [Ti3Cl8(NPMe3)3]+ are linked by two /x3-N atoms of two NPMe3~ groups forming a distorted trigonal-bipyramidal arrangement. The third NPMe3_ group and two of the chlorine atoms have /i2-bridging functions. The mixed-valence complex [V2Cl4(NPPh3)3] is formed as dark green moisture sensitive crystals by the reaction of vanadium trichloride with Me3SiNPPh3 in boiling toluene. According to the crystal structure determination the vanadium atoms are linked by two /z2-N atoms of two NPPh3_ groups forming a nonplanar V2N2 four-membered ring with a V-V distance of 266.8(1) pm which corresponds to a (a, 1/27r) bond type. This is confirmed by the measurement of the magnetic susceptibility which leads to a magnetic moment of 1.45(5) B. M., corresponding to the remaining d 1 -electron.
