| Abstract: A novel coordination polymer of [Sr2(4-CPOA)2(H2O)5]n (where 4-CPOA2- is 4-carboxylphenoxyacetate) has been synthesized and characterized by elemental analysis, IR, TG and single crystal X-ray diffraction. The title complex belongs to monoclinic system with space group C2/c, a=2.563 9(5) nm, b=1.162 7(2) nm, c=0.742 96(15) nm, β=99.64(3)°. V=2.183 5(7) nm3, Z=4, Mr=653.60, Dc=1.988 g·cm-3, R=0.027 8, wR=0.058 1. The strontium atom has a bicapped triangular prismatic coordination geometry, involving four oxoacetate oxygen atoms, one ether oxygen atom from different 4-CPOA2- ligands and three water molecules. The strontium(Ⅱ) ions are linked by 4-CPOA2- ligands and water molecules to form a 3D network structure. CCDC: 223313. |
