[(-)-(1S,2S)-N,N′-Bis(2-oxidobenzylidene)-1,2-diphenylethane-1, 2-diamine]-bis-(pyridine)cobalt(III) perchlorate methanol hemisolvate hemihydrate

Abstract

In the title compound, [Co(C28H22N2O2)(C5H5N)2]ClO4·0. 5CH4O·0.5H2O, each CoIII ion is coordinated by the tetra-dentate N,N′-bis-(2-oxidobenzyl-idene)-1,2-diphenyl-ethane-1,2- diamine ligand [Co - N = 1.900 (3) and 1.903 (3) Å Co - O = 1.885 (3) and 1.891 (3) Å] and two pyridine ligands [Co - N = 1.967 (4) and 1.977 (3) Å] in a distorted octa-hedral geometry. The packing of the cations and anions forms voids of 258 Åκ3, which are filled by methanol and solvent water mol-ecules with half occupancies. O - H⋯O hydrogen bonds between solvent molecules, perchlorate anions and water molecules, and between water molecules and O atoms of the ligand, help to consolidate the crystal packing.
