一个新的钴磷酸盐配合物Co(μ3-O3P)·H2O的合成与晶体结构

A new layered cobalt phosphate complex, Co( μ₃-O₃P)·H₂O, was prepared by the hydrothermal reaction. The crystal structure of the complex was determined by single-crystal X-ray diffraction. The results indicate that it contains two different infinite PO₃chains linked by CoO₆ octahedra with infinite 1-D tunnels. It crystallizes in the orthorhombic space group Pbcm with a=0.790 12(16) nm, b=0.900 25(18) nm, c=1.016 1(2) nm, β=90°, V=1.245 3nm³, Z=4. Refinement gave R₁=0.068 5, wR₂=0.175 1 for 2 133 unique observed reflections (I>2σ(I)). The title complex was also characterized by IR, TG-DTA and chemical analysis. CSD: 413934.
