Synthesis of new Bismuth (III) compound and adducts of benzothiazol disulfide derivatives and their complexes with Co(II), Ni(II) and Cu(II)

Abstract

Abstract Bismuth metal react with dibenzothiazole disulfide (C7H4NS2)2 in refluxing toluene to give the compound Bi(S2C7H4N)3 through oxidative addition reaction, similary, a mixture of bismuth, (C7H4NS2)2 and iodine in 1:1:0.5 molar ratio in refluxing toluene lead to the formation of Bi(S2C7H4N)2I. Adducts of new bismuth compounds with triphenyl-phosphine and 1,10-phenanthroline have been synthesized by direct reaction between the bismuth compounds and the neutral ligand. Trinuclear complexes of the general formula[Bi(S2C7H4N)3(MCl2)2] were prepared by a direct reaction of CoCl2.6H2O, NiCl2.6H2O or CuCl2.4H2O with bismuth compound. The bismuth compounds their adducts and the complexes have been characterized physico-chemically and spectro-scopically.
