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]·(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.
