Studies on cobalt(II) complexes with N-thioacylamido(thio)phosphates: X-ray crystal structure of the Co[PhC(S)NP(S)(OPri)2]2

Reaction of the potassium salts of N-thioacylamidophosphates RC(S)NHP(O)(OPri)2 (R = Ph, PhNH, p-MeOPhNH, p-BrPhNH, iPrNH, tBuNH, Et2N, c-C5H10N, c-OC4H8N, c-C5H11NH) with Co(II) cation in aqueous EtOH leads to the complexes of Co(L-O,S)2 type structure. Complexes Co(B)L2 were obtained by the reaction of chelate complexes CoL2 (R = Ph, PhNH) with 2,2′-bipyridine and 1,10-phenanthroline. Structures of the compounds obtained were investigated by EIMS, IR, UV–Vis spectroscopy and microanalysis. Complex Co[PhC(S)NP(S)(OPri)]2 was investigated by single crystal X-ray diffraction.

Unsaturation of CoO2S2 coordination environment opens opportunities for wide number of heteroligand complexes synthesis. It can be reached by interaction of such complexes with various donor agents. As donors, both monodentate ligands and chelating agents might be used. A variety of donors structure opens wide prospects for supramolecular units with in advance set properties synthesis. 2,2′-Bipyridine and 1,10-phenanthroline were used in our work as donor ligands.Figure optionsDownload as PowerPoint slide
