Synthesis and Structural Characterization of a Cobalt Coordination Polymer with Bis(4-(1H-imidazol-1-yl)phenyl)methanone and 4-Nitrophthalate
A cobalt coordination polymer having the formula of [Co(npa)(L1)(H2O)2]n (1), where L1 is a bis(4-(1H-imidazol-1-yl)phenyl)methanone and H2npa is a 4-nitrophthalic acid, has been synthesized and structurally characterized. Single crystal X-ray diffraction analysis shows that the Co1 has a distorted octahedral geometry with four O atoms from two npa2– ligands and two N atoms from two L1 ligands, while the Co2 has the same coodination geometry with four O atoms from coordinating water molecules and two N atoms from two L1 ligands. Each L1 acts as a bridging ligand to link neighboring Co ions to form a 1D chain.
