A Dimeric Copper(II) Complex of an α-Hydroxylated Acid: [Cu(C₁₄H₈O₃)(C₉H₇N)(H₂O)]₂.2C₃H₇NO.2H₂O

The structure of bis[μ-(9-hydroxy-1:2κ²O)-9-fluorenecarboxylato(2-)]-1κO; 2κO-bis[aqua(quinoline-κN)copper(II)] bis(dimethylformamide) dihydrate has been determined by single-crystal X-ray diffraction. The binuclear Cu^II unit comprises a pair of Cu atoms linked by two hydroxyl O-atom bridges. The coordination polyhedron around each Cu atom is a distorted square pyramid, the basal plane consisting of one N atom from the quinoline ligand, one carboxyl O atom and two bridging O atoms from two α-hydroxylated acid ligands, while the axial coordination site is occupied by an O atom of the coordinated water molecule with a Cu—O bond length of 2.424 (4) Å.
