摘要：

The amidinato complexes [Ph-C(NSiMe3)2TlCl2] and [Ph-C(NHSiMe3)2][Ph-C(NSiMe3)2TlCl3] have been prepared by the reaction of TlCl3 with N,N,N'-tris(trimethylsilyl)benzamidine in THF solution. They were characterized by IR spectroscopy, [Ph-C(NHSiMe3)2][Ph-C(NSiMe3)2TlCl3] additionally by an X-ray structure determination. Space group P2(1)/c, Z = 4, 4300 observed unique reflexions, R = 0.053. Lattice dimensions at -43-degrees-C: a = 1157.2, b = 2346.3, c = 1536.9 pm, beta = 105.98-degrees. The structure consists of amidinium cations, and of anions [Ph-C(NSiMe3)2TlCl3]-, in which the thallium atom is fivefold surrounded by three chlorine atoms and by two nitrogen atoms of the amidinato chelate.
