A new binuclear copper complex,[Cu₂L₂(pht)₂]₂·H₂O (Hpht=5,5-diphenylhydantoin, i.e. phenytoin; L=2-diethylaminoethanol), has been synthesized by the solvothermal method, and characterized by elemental analysis, IR and single-crystal X-ray diffraction. The crystal belongs to the monoclinic system, space group C2/c with a=31.918(3), b=12.9222(15), c=19.868(2) Å, β=98.762(2)°, V=8098.8(16) Å³, Dc=1.429 Mg/m³, Z=4, F(000)=3640, μ=1.107 mm^-1, R=0.0560 and wR=0.1276 (I > 2σ(I)). Each copper(Ⅱ) in a molecule is coordinated with N and O atoms from ligand L and N atom from ligand Hpht in a tetradentate manner. Moreover, two copper(Ⅱ) centers are bridged by two O atoms of hydroxyl groups from two L ligands to form a slightly distorted binuclear {Cu₂O₂} diamond configuration. In addition, the interaction of this complex with calf thymus DNA (CT-DNA) was investigated by UV-vis spectrum and viscometry, and the complex may bind to DNA through intercalation.
