Crystal structures and physicochemical studies of some novel divalent and trivalent transition metal chelates of N-morpholine-N'-benzoylthiourea

•Co(III), Cu(II), Fe(III), In(III), Ni(II), and Zn(II) thiourea complexes have been synthesized.•Elemental analysis, TGA, FTIR, 1H NMR spectroscopy and X-ray crystallography studies are reported.•The ligand coordinates the various metal ions in a bidentate (L-kO,S) chelating mode.•The complexes are potentially useful as single source molecular precursors for metal sulfide nanomaterials.
