| Abstract: A hydrated tetra-carboxylato-bridged dinuclear copper(Ⅱ) complex [Cu2(mEP)2(H2O)2]2 (1) (mEp is mono -ethyl phthalate or 1,2-benzenedicarboxylate monoethyl ester) has been prepared and characterized by X-ray diffraction single crystal structure analysis and magnetic measurements. This dinuclear complex adopts dimeric paddle-wheel cage structure and the coordination model around each copper(Ⅱ) atom is square-pyramidal with four oxygen atoms of the carboxylate groups from four different mono-ethyl phthalate ligands and one oxygen atom of water as apical position. The magnetic data for 1 exhibited strong intramolecular antiferromagnetic interaction between the two paramagnetic metal ions with 2J=-315.18 cm-1. Comparing with other related complexes in structure and magnetic propertity, the main factor which determines the strong antiferromagnetic interaction in the dimeric copper(Ⅱ) carboxylates is the electronic structure of the bridging O-C-O moiety. CCDC: 624561. |
