A new mononuclear tin(IV) complex [Sn(edt)2L]?CH2Cl2 (edt = ethane-1,2-dithio- late, L = di-2-pyridyl-ketone p-phenyldiamine) was obtained by a one-pot reaction which involves in situ formation of a new Schiff-base ligand L. The title compound (C22H24Cl2N4S4Sn) crystallizes in monoclinic, space group P21/n with a = 13.438(1), b = 12.2657(10), c = 17.1477(13) ?, β = 99.323(1)o, V = 2789.1(4) ?3, Z = 4, Mr = 662.28, Dc = 1.577g/cm3, F(000) = 1328, μ = 1.426 mm?1, the final R = 0.0450 and wR = 0.1077 for 3868 observed reflections (I > 2σ(I)). In the title compound, Sn4+ 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.
