A one-dimensional cobalt(II) coordination polymer based on 2,4'-oxydibenzoic acid: Poly[[[diaquabis[2-(4-carboxyphenoxy)benzoato- κO1]cobalt(II)]-μ-4,4'-bipyridine-κ2 N:N'] dihydrate]

摘要

The reaction of CoSO4 with 2,4-oxydibenzoic acid (H 2oba) and 4,4'-bipyridine (bipy) under hydrothermal condition yielded a new one-dimensional cobalt(II) coordination polymer, {[Co(C 14H9O5)2(C10H 8N2)(H2O)2]2H2O} n , which was characterized by elemental analysis, IR spectroscopy, thermogravimetric analysis, magnetic properties and single-crystal X-ray diffraction. The CoII ions are connected by bipy ligands into infinite one-dimensional chains. The Hoba- ligands extend out from the two sides of the one-dimensional chain. O-H?O hydrogen bonding extends these chains into a two-dimensional supramolecular architecture.
