The title compound, lead bismuth calcium sodium phosphate, Pb(4.6)Bi(0.4)Ca(2.6)Na(2.4)(PO(4))(6) crystallizes in the apatite structure type, with vacancies in sites 2a or 2b that are normally occupied by anions. The fact that the Bi and Pb ions are mainly localized in the 6h sites confirms the electron lone-pair influence on the apatite structure.
