2,2-diphenyl-N-(R-carbamothioyl)acetamide (R = diethyl, dipropyl, dibutyl, dihexyl, diphenyl and morpholine-4) and their Ni2 and Cu2 complexes have been synthesized and characterized by elemental analyses, IR spectroscopy and 1H-NMR spectroscopy. The spectroscopic data are consistent with the ligand and the metal complexes containing two O, S chelated ligands. 2,2-diphenyl-N-(diethylcarbamothioyl)acetamide, HL1, and bis(2,2-diphenyl-N-(diethylcarbamothioyl)acetamido)nickel(II), Ni(L1)2, were characterized by a single crystal X-ray diffraction study. HL1 complex, C19H22N2OS, crystallizes monoclinic, space group P21/c, with Z = 4, and unit cell parameters a = 14.964(2), b = 13.026(2), c = 9.0123(15) Å, β = 96.314(4)°. Ni(L1)2 complex, C38H42N4O2S2Ni, crystallizes in monoclinic space group P21/c, with Z = 4, and unit cell parameters a = 15.434(6), b = 13.464(5), c = 17.679(7) Å, β = 108.477(11)°. The ligands coordinate bidentate to metal yielding neutral complexes of the type cis-[ML2].
