Three Dimensional Structure

The title compound, [Co(C17H13N2O2)2(C2H5OH)2], is a CoIIcomplex with two 4-benzoyl-3-methyl-1-phenyl-1H-pyrazol-5-olate (BMPP) ligands and two coordinating ethanol molecules. In the asymmetric unit, there are two half molecules, with the CoIIatoms located on inversion centres. The two cobalt complexes have slightly different geometries and in one, the ethyl group of the ethanol is disordered over two sets of sites [occupancy ratio 0.757 (7):0.243 (7)]. Each BMPP ligand is deprotonated with the negative charge delocalized. The hydroxy group of each ethanol molecule forms hydrogen bonds with a pyrazole N atom in an adjacent BMPP ligand. Weaker C—H...O and C—H...N interactions link the molecules into a three-dimensional structure.
