Mixed solvothermal synthesis and X-ray characterization of a layered copper coordination polymer, Cu(H_2O)(1,3-BDC)·H_2O (BDC=benzenedicarboxylate)

摘要

A novel copper coordination polymer,Cu(H_2O)(1,3-BDC)·H_2O was synthesized bya mixed solvothermal reaction of cupric acetate with 1,3-BDC and characterized by single-crystal X-ray diffraction.This compound crystallizes in a tetragonal space group P4mm with cell parameters a=19.1411(5) A,c=6.7881(2)A,and Z=8.Its structure contains paddle-wheel-like bi-copper clusters with the pseudo-octahedral centers of Cu(II)ion,Cu_2O_8(H_2O)_2.Every 1,3-BDC fragment links two such clusters to yield a two-dimensional open structure. It was also characterized by infrared spectroscopy,elemental analysis,inductively coupled plasma analysis,differential thermal and thermal gravimetric analyses.
