Synthesis, Crystal Structure, and Luminescent Property of a Ba(II) Coordination Polymer Based on Naphthalene-1,4,5,8-tetracarboxylic Acid 1,8-anhydride

A new coordination polymer, [Ba(ntcaa)2·DMF]n (1) (ntcaa = naphthalene-1,4,5,8-tetracarboxylic acid 1,8-anhydride, DMF = N,N-dimethylformamide), has been hydrothermally synthesized and characterized by single-crystal X-ray diffraction, IR, element analysis, and thermal analysis. The compound 1 shows a two-dimensional layer structure constructed by main group metal Ba and carboxylate ligand ntcaa. In additional, the luminescent property of 1 is investigated.
