A novel binuclear copper(II) complex with 2-(methoxycarbonyl)benzoic acid (HL), N,N-dimethylformamide (DMF) and methanol [Cu2L4(DMF)(CH3OH)·CH3OH] was synthesized. The complex was crystallized in the monoclinic system. The space group was Pn with a = 14.410(3)Å, b = 10.540(2)Å, c = 14.496(3)Å, β = 91.082(4)°, V = 2201.4(9)Å3 and Z = 2. The final R value was 0.0227. Each Cu(II) ion is coordinated by four carboxylate O donor atoms from four ligands, and by O donor atoms from the solvent molecule, DMF for Cu(1); for Cu(2) it is the O atom of methanol. The whole molecule looks like a “pedal-wheel”. The O-H…O hydrogen bonds between the compound and the solvent molecule stabilize the crystal structure by causing the formation of a one-dimensional chain structure.
