Abstract

An in situ ligand reaction from the pyridine cycle to -COO- in the copper-organic framework is achieved under hydrothermal conditions. Compound [Cu2(bpa)4] [1; bpa=5-(4-bromophenyl)picolinic acid] exhibits a one-dimensional chain architecture based on weak Cu-O interactions. The mechanism of ligand transformation is discussed.
