Pressing solid barbituric acid with KBr to prepare samples for IR spectroscopy leads the formation of an ionic co-crystal, in which co-former is a classical salt; co-crystal also obtained other alkali bromides (LiBr, NaBr, RbBr and CsBr) caesium iodide. The simultaneous presence halide ions affects dissolution properties water.
