In this work, we have carried out systematic structural investigations of single crystals and ceramics with several compositions across the phase boundary. The phase diagram for x <= 0.07 has been established. A complex phase coexistence is found near the phase boundary, which leads to an unusual transition sequence. It is confirmed that Pbam and R3c structures maintain a subtle balance at the phase boundary, which may be perturbed by a slight change in the concentration or external stimuli. These findings provide unique insights into understanding the antiferroelectric-ferroelectric competition and, hence, into designing alternative materials for energy storage and conversion.
