Abstract

[TcO(C8H18N2S2)]TcO4, Mr = 484.2, monoclinic, P2(1)/c, a = 7.447 (2), b = 16.952 (8), c = 12.236 (3) A, beta = 99.63 (2) degrees, V = 1523 (1) A3, Z = 4, D chi = 2.112, Dm = 2.09 (1) Mg m-3, lambda(Mo K alpha) = 0.71069 A, mu = 2.06 mm-1, F(000) = 952, T = 295 (1) K, final R = 0.071 for 2496 significant reflections and 173 parameters. The Tc atom is bound to the oxo group and the N and S atoms of the complex ligand in a rough square pyramid. The Tc atom lies 0.770 (3) A out of the S,N,N',S' plane. This plane is significantly distorted such that N and N' lie nearly 0.25 A out of the plane on opposite sides. The Tc-S bonds [2.238 (3), 2.266 (3) A] are short but other bond lengths and angles are normal.
