pH-Controlled change of the coordination modes of the highly symmetrical multitopic ligand and metal–oxygen arrays for constructing coordination assemblies

Abstract

For the first time, the effect of the pH value on the coordination assemblies of a highly symmetrical multitopic ligand has been systematically investigated, indicating that higher pH values lead to increase of the coordination ability of the ligand, the amount of hydroxide incorporated into the structures, and the degree of condensation of metal polyhedra in the resulting 3D networks.
