The lowest symmetry acentric network polymer with cavities resulted from two distinct metal centers with multifunctional ligands decorating the walls of the framework

The reported structure of the new MOF coordination polymer has following features:•The structure has two distinct metal centers with multifunctional ligands decorating walls.•The structure displayed the lowest possible symmetry.•It has walls decorated with free sites having potential binding sites.

A new MOF coordination polymer, [(H2O)Cu(BNA)4)Cu(H2O)(BPY)]∙ 5H2O (BNA = 5-bromonicotinato C6H3NO2Br; DPY = 4,4′-dipyridyl C10H8N2), with two distinct metal centers with multifunctional ligands decorating the walls of the framework has been synthesized. The structure is crystallized with the lowest symmetry P1, which displayed an acentric network with inclusion water molecules in the cavities.

Graphical abstractAn acentric coordination polymer with two distinct metal centers with multifunctional ligands decorating the walls of the framework has been synthesized. The structure is crystallized with the lowest symmetry P1 with inclusion water molecules. The MOFs with walls decorated with free sites for possible chemical bindings have attracted more interests.Figure optionsDownload full-size imageDownload as PowerPoint slide
