{6,6'-Diethoxy-2,2'-[2,2-dimethylpropane-1,3-diylbis(nitrilomethylidyne)]diphenolato}(2-ethoxy-6-formylphenolato)cobalt(III)-ethanol-water (1/1/1)

Abstract: The asymmetric unit of the title compound, [Co(C₂₃H₂₈N₂O₄)(C₉H₉O₃)]·C₂H₅OH·H₂O, comprises one complex molecule, a water molecule of crystallization and an ethanol molecule of crystallization, which is disordered over two positions with a ratio of refined site occupancies of 0.567 (10):0.433 (10). The Co^III ion is in a slightly distorted octahedral geometry involving an N₂O₂ atom set of the tetradenate Schiff base ligand and two O atoms of 2-ethoxy-6-formylphenolate. The H atoms of the water molecule act as donors in the formation of bifurcated intermolecular O-H(O,O) hydrogen bonds with the O atoms of the hydroxy and ethoxy groups with R₁²(5) ring motifs, which may influence the molecular conformation. The crystal structure is further stabilized by intermolecular O-HO and C-HO interactions.
