New BPTH-Bridged Chained Cd(II) Coordination Polymer Based on Cd2O2 Clusters: Synthesis and Crystal Structure of [Cd(BPTH)(phen)]·3.75H2O (BPTH = biphthalhydrazidate; phen = phenanthroline)

摘要

Based on the hydrothermal in situ acylation reaction of 4,4′-biphthalic acid (bpha) with N2H4·H2O, a new acylhydrazidate-bridged 1-D chained Cd2+ coordination polymer [Cd(BPTH)(phen)]·3.75H2O (BPTH = 4,4′-biphthalhydrazidate, phen = phenanthroline) was synthesized, and characterized by elemental analysis, infrared spectroscopy, powder X-ray diffraction (XRD), thermogravimetric analysis and single-crystal XRD. With ancillary phen molecules, the BPTH molecules link the Cd2+ centers into a 1-D staircase chain structure of compound 1 based on the Cd2O2 clusters.
