A new paddle-wheel Cu(II) complex having formula [Cu(L)2(DMF)] (1)  (HL = 2-fluorobenzoic acid) has been synthesized and characterized using FTIR and single crystal X-ray diffraction. The single crystal X-ray diffraction study indicates that the carboxylic acid ligand adopt bridging bidentate modes to coordinate Cu(II) centers thereby forming a binuclear copper(II)carboxylate type structure. The complex has been utilized as photocatalyst to photodegrade model aromatic dyes viz. methyl violet (MV) and rhodamine B (Rh B) in UV light. The photocatalytic results indicated that1 offered moderate photocatalytic activity and offers good stability after performing photocatalysis. The plausible mechanism through which 1 exerted photcatalytic property had been proposed by using density of states (DOS) and partial DOS calculations.
