| Abstract: | The synthesis, characterisation and properties of two trans nickel(II) complexes with thiocyanate coordination. [Ni(L1)(NCS)2] (1) and Ni(L2)(NCS)2] (2) and comparison of the results with cis-[Mn(L1)(NCS)2] (3) and cis-[Mn (L2)(NCS)2] (4) (L1 and L2 = tetradentate ligands, derived from bis condensation between pyridine-2- carboxaldehyde and 1, 3-diaminopropanc and 2-benzoyl pyridine and 1,3-diaminopropane respectively) are described. The structures have been determined by single crystal X-ray diffraction studies. Study reveals that the nickel atom always produces trans isomer and manganese atom gives the cis isomer. Both metals are hexacoordinated with an unusual preferential binding of tetradentate ligands and thiocyanate anions. |
