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.
