New diorganotin(IV) complexes of the type Ph2SnL2, Bu2SnL2 and Me2SnL2 of the ligands 2-thioacetic-5-phenyl-1,3,4-oxadiazole (HL) and benzamidophenylalanine (HL). Have been synthesized and characterized by physico-chemical techniques such as (elemental analysis, and electrolytic conductance) and spectral UV-Visible, IR and H, C and Sn NMR). Monomer structures for the complexes, bidentate and oc...
