A novel Ca(Ⅱ) coordination polymer,[CaL2(H2O)2]n (1,HL =4-acetylphenoxyacetic acid) has been synthesized with 4-acetylphenoxyacetic acid,Ca(ClO4)2·4H2O and NaOH as raw materials.Complex 1 was characterized by elemental analysis and single-crystal X-ray diffraction analysis.The results show that the Ca(Ⅱ) ion is eight-coordinated in a distorted triangular dodecahedral geometric configuration with six carboxylate O atoms of four L ligands and two O atoms of two coordinated water molecules.Complex 1 forms a one-dimensional chained structure by the bridging effect of carboxylate O atoms.The antitumor activity of HL ligand and complex 1 has also been investigated.
