The title compound （C22H24C12N484Sn） crystallizes in monoclinic, space group P211n with a = 13.438（1）, b = 12.2657（10）, c = 17.1477（13） k,, β = 99.323（ 1 ）°, V = 2789.1 （4） A, Z = 4, Mr = 662.28, Dc= 1.577g/cm^3, F（000） = 1328,μ= 1.426 mm^-1, the final R = 0.0450 and wR = 0.1077 for 3868 observed reflections （1 〉 2σ））. In the title compound, Sn^4＋ ion is six-coordinated with four sulfur atoms of two edt ligands and two nitrogen atoms of the ligand di-2-pyridyl-ketone p-phenyldiamine to form a highly distorted octahedron.展开更多
