Bis(thiocyanato-N)[tris(2-pyridylmethyl)amine-⁴N,N',N'',N''']nickel(II) methanol hemisolvate

S. R. Randeniya and R. E. Norman

Abstract: The title complex, [Ni(NCS)₂(C₁₈H₁₈N₄)]·0.5CH₃OH, consists of two crystallographically distinct complexes and a methanol solvent molecule. The Ni^II complexes are pseudo-octahedral six-coordinate, with the tris(2-pyridylmethyl)amine (TPA) ligand providing four N atoms and two N-bound thiocyanates providing the final two N atoms. The distances and angles are typical for Ni^II-TPA complexes. The compound has unit-cell parameters that are surprisingly similar to the previously reported hydrate.
