Synthesis and crystal structure of trinuclear zinc coordination polymer based on a triangle flexible carboxylic ligand

Flexible carboxylic ligands have attracted considerable interest due to their excellent stretchable capacity and coordinative ability. In this paper, one new 2D zinc coordination polymer {[Zn(tcpob)(2/3)(H2O)(2/3)]center dot(H2O)(2/3)}(n) with trinuclear zinc cluster units was prepared under hydrothermal conditions based on 1,3,5-tri(4-carboxyphenoxy)benzene ligand. In addition, the solid-state photoluminescent spectra were measured at room temperature. Published by Elsevier B.V.
