Abstract
In the title complex, [Co(C22H15O5)2(C2H5OH)2], the CoII atom (site symmetry ) is coordinated by two O,O′-bidentate 4-(2-benzoyl-1-oxidoethenyl)-3-hydroxyphenyl benzoate anions and two ethanol O atoms, resulting in a slightly distorted CoO6 octahedral coordination. An intramolecular O—H⋯O hydrogen bond in the ligand generates an S(6) ring. The dihedral angle between the aromatic rings joined to the acetylacetonate unit is 6.4 (2)°. The ethanol molecule is disordered over two orientations in a 0.65 (3):0.35 (3) ratio. In the crystal, molecules are linked by O—H⋯O bonds.

Summary
Key indicators: single-crystal X-ray study; T = 298 K; mean (C–C) = 0.007 A; disorder in main residue; R factor = 0.065; wR factor = 0.161; data-to-parameter ratio = 12.6. In the title complex, [Co(C22H15O5)2(C2H5OH)2], the CoII atom (site symmetry 1) is coordinated by two O,O0-bidentate 4-(2-benzoyl-1-oxidoethenyl)-3-hydroxyphenyl benzoate anions and two ethanol O atoms, resulting in a slightly distorted CoO6 octahedral coordination. An intramolecular O—HÁ Á ÁO hydrogen bond in the ligand generates an S(6) ring. The ethanol molecule is disordered over two orientations in a 0.65 (3):0.35 (3) ratio. Molecules are linked by O—HÁ Á ÁO bonds. Crystal data [Co(C22H15O5)2(C2H6O)2] Mr = 869.75 Triclinic, P1 a = 7.2068 (9) Ab = 9.4298 (12) Ac = 16.5511 (19) A = 106.358 (1) = 95.431 (2)
