The complex {[Cd2(C 9H8O3N) 2(CH3COO) 2(4, 4'-bipy) 2] (4, 4'-bipy) -(H 2O) 4} n with 4-acetamidobenzoic acid and 4, 4' -bipyridine has been synthesized with liquid diffusion method and characterized. It crystallizes in the monoclinic space group C2/c. The crystal structure shows that two neighboring cadmium (II) ions are linked together by two bridging acetic acid radicals, forming a binuclear structure. Adjacent binnuclear structure is linked together by two bridging 4, 4'-bipy molecules and the complex molecule forms an one-dimensional double-chain structure....
