摘要：

[Tl(Cl)2(I){P(C6H5)O}2], M(r) = 958.77, monoclinic, P2(1)/c, a = 14.738 (1), b = 14.466 (6), c = 17.194 (1) angstrom, beta = 107.98 (1)-degrees, V = 3486.7 angstrom 3, Z = 4, D(x) = 1.826 g cm-3, Mo K-alpha, lambda = 0.70930 angstrom, mu = 58.3 cm-1, F(000) = 1840, T = 223 K, final R = 0.062 for 4967 significant [I > 3-sigma(I)] reflections. The structure consists of discrete TlCl2I(tppo)2 molecules (tppo = triphenylphosphine oxide) which have a distorted trigonal bipyramidal geometry. The Tl atom is coordinated to two Cl atoms and an I atom in equatorial positions, Tl-Cl = 2.412 (2) and 2.400 (5) angstrom, and Tl-I = 2.635 (2) angstrom, and by two tppo ligands in axial positions, Tl-O = 2.38 (2) angstrom. The crystal structure is isotypic with those of TlBr3(tppo)2, TlBr2I(tppo)2, TlBrI2(tppo)2 and TlClBrI(tppo)2.
