摘　　要：Two mononuclear tin(IV) complexes, [Sn(pda)2(edt)2] (pda = o-phenylenediamine) (C16H24N4S4Sn, Mr = 519.32) 1 and [Sn(eda)(edt)2] (eda = ethylenediamine) (C6H16N2S4Sn, Mr = 363.14) 2 were synthesized and characterized by X-ray structure analysis. 1 belongs to trigonal, space group P-3c1 with a = b = 20.0280(6), c = 8.7679(5) ? V = 3045.8(2) ?, Z = 6, Dc = 1.699 g/cm3, m = 1.677 mm-1, F(000) = 1572, the final R = 0.0418 and wR = 0.1019 for 1805 independent reflections. 2 crystallizes in monoclinic, space group P21/c with a = 10.911(3), b = 9.783(2), c = 11.831(3) ? b = 100.28(2), V = 1242.6(6) ?, Z = 4, Dc = 1.941 g/cm3, m = 2.690 mm-1, F(000) = 720, the final R = 0.0280 and wR = 0.0627 for 2166 independent reflections. Both Sn4+ ions in these two complexes are six-coordinated with a slightly distorted octahedral configu- ration.Two mononuclear tin(IV) complexes, [Sn(pda)2(edt)2] (pda = o-phenylenediamine) (C16H24N4S4Sn, Mr = 519.32) 1 and [Sn(eda)(edt)2] (eda = ethylenediamine) (C6H16N2S4Sn, Mr = 363.14) 2 were synthesized and characterized by X-ray structure analysis. 1 belongs to trigonal, space group P-3c1 with a = b = 20.0280(6), c = 8.7679(5) ?
