When the energy landscape offers numerous low-energy structures, the synthetic method can determine which structure is formed. In solid-state reactions yielding new crystalline extended structures from solid precursor phases, mass transport coupled with pronounced reorganization of atomic coordination environments is required. The picture shows the reaction of BaO (left) with TiO2 (right) to form BaTiO3 (middle).
