ž-phth (phthalic acid dianion), having two isolated metal-binding groups, together with X ligand (X = CH3CO2 _, CF3 CO2 _ and Ph-CO2 _ ) formed dicobalt(II) complexes [Co2(II)(ž-phth)(ž-CH3CO2 _ )(bipy)2]ClO4 (1), [Co2(II)(ž-phth)(ž-CF3CO2 _ )(bipy)2]ClO4 (2) and [Co2(II)(ž-phth)(ž-Ph-CO2 _ )(bipy)2]ClO4 (3). Their structure was characterized spectroscopically and magnetically, presenting a ž-phth-ž-X-bridged dinuclear structure. The pair of cobalt ions bridged by CH3COO undergoes antiferromagnetic coupling. Catalytic properties for H2O2 dismutation are reported for complex 1-3.
