Synthesis, characterization, magnetic properties of cobalt coordination polymer based on 4,4'-Oxybisbenzoic acid and 1,4-bis(pyrid-4-yl)benzene

摘要

A compound with cation chains and monomers, [Co_(1/2)(bpbenz)_(1/2)]~+ [Co_(1/2)(oba)]~-(1) (bpbenz =1,4-bis(pyrid-4-yl)benzene and H_2oba =4,4'-Oxybisbenzoic acid) has been synthesized under hydrothermal condition. Single crystal X-ray diffraction analyses reveal that in compound 1, the monomer [Co_(1/2)(oba)]~-anions stack in three orientations to generate a 1D pseudo channels encapsulation of cationic chains [Co_(1/2)(bpbenz)_(1/2)]~+. Magnetic studies indicate that compound 1 exhibit weak antiferromagnetic interactions.
