Polymorphism of the dinuclear Co^III-Schiff base complex [Co₂(o-van-en)₃]·4CH₃CN (o-van-en is a salen-type ligand).

ABSTRACT: Reactions of Co(OH)₂ with the Schiff base bis(2-hydroxy-3-methoxybenzylidene)ethylenediamine, denoted H₂(o-van-en), under different conditions yielded the previously reported complex aqua[bis(3-methoxy-2-oxidobenzylidene)ethylenediamine]cobalt(II), [Co(C₁₈H₁₈N₂O₄)(H₂O)], 1, under anaerobic conditions and two polymorphs of [μ-bis(3-methoxy-2-oxidobenzylidene)ethylenediamine]bis{[bis(3-methoxy-2-oxidobenzylidene)ethylenediamine]cobalt(III)} acetonitrile tetrasolvate, [Co₂(C₁₈H₁₈N₂O₄)₃]·4CH₃CN, i.e. monoclinic 2 and triclinic 3, in the presence of air. Both novel polymorphs were chemically and spectroscopically characterized. Their crystal s
