The coordination polymer of [Mn(p-CPOA)(H2O)3]n (p-CPOA=4-carboxylphenoxyacetate) was synthesized and characterized by elemental analysis, IR, X-ray single crystal diffraction. The title complex crystallizes in mono-clinic with space group P21/c, a=0.699 8(1) nm, b=1.6235(3) nm, c=1.014 3(2) nm, β=99.55(3)°.

The manganese atom is seven-coordinate involving four oxygen atoms of different p-CPOA2- ligands and three coordinated water, forming a distorted pentagonal bipyramindal environment. Two manganese atoms are bridged by p-CPOA2- ligand, forming a one-dimensional zigzag chain structure along p axis. The adjacent distance of Mn…Mn atoms is 1.021 0 nm. The three-dimensional hydrogen bonding network was formed by the intermolecular hydrogen bonds. CCDC: 219358. 相似文献
