Reactions between triorganotin chloride and 2,5-dimercapto-4-phenyl-1,3,4- thiodiazole gave complexes R3Sn(S3N2C8H5) (4: R = Ph; 5: R = PhCH2 and 6: R = n-Bu), respectively. All products were characterized by elemental analysis, IR, 1H NMR, 13C NMR, and two of them ((4) and (5)) have been determined by X-ray crystallography. Including the Sn-N interaction, the tin atoms of three complexes all have five-coordinated distorted trigonal bipyramidal geometry. All three complexes have antitumor activity in bioactivity measurements. Crystal data for complex (4): monoclinic, space group P2(1)/c, a = 9.696(2)A,b = 14.773(3) A, c = 17.466(4)A, _ = 92.599(3)_, and Z= 4. Crystal data for complex (5): triclinic, space group P-1, a = 9.744(6) A, b = 16.338(10) A, c =17.957(12) A, _ = 90.000(12)_, _ = 100.735(11)_, _ = 90.000(12)_ and Z = 4.
