{(+)-(1R,2R)-1,2-Diphenyl-2,2′-[ethane-1,2-diylbis(nitrilomethylidyne)]diphenolato}dipyridinecobalt(III) perchlorate sesquihydrate

Abstract

In title complex, [Co(C28H22N2O2)(C5H5N)2]ClO4·1.5H2O, the CoIII ion is in a slightly distorted octa­hedral coordination environment with the pyridine ligands in a trans arrangement. In addition to the cation and anion, the asymmetric unit also contains three half-occupancy solvent water mol­ecules and all components are connected via inter­molecular O—H⋯O hydrogen bonds.
