A 1D Linear Chain Coordination Polymer Constructed by Co(II) with Atibdc and Bipy Ligands (H2Atibdc = 5-Amino-2,4,6-triiodoisophthalic Acid, Bipy = 4,4-Bipyridyl)

摘要

Anew coordination polymer, [Co(Atibdc)(Bipy)(H2O)3]·2DMF·H2O (I) (H2Atibdc = 5-ami-no-2,4,6-triiodoisophthalic acid, Bipy = 4,4'-bipyridyl), has been synthesized and characterized by elemental analysis, IR, and X-ray single-crystal diffraction. The X-ray diffraction analysis reveals that I (C24H_(30)CoI3N5O_(10)) crystallizes in the monoclinic system, space group P2_1. The adjacent cobalt atoms adopt different coordination modes via nitrogen atoms from two different Bipy ligands to generate an infinite linear chain, which are further linked by hydrogen bonds and I-I weak interactions to form a two-dimensional layer.
