Abstract

The chloroapatite Eu5(PO4)3Cl has been synthesized by a solid-state reaction route using a salt flux. Its structure has been solved and refined from single crystal X-ray data: apatite type, P6 3/m, a = 988.36(4), c = 720.32(3) pm, Z = 2, R(F) = 0.021 and wR(F2) = 0.063 for 748 unique reflections and 40 variables. The Eu5(PO4)3Cl structure contains isolated (PO4)3- tetrahedra and two crystallographically independent divalent europium sites. The Eu12+ ion at the 4f position is located in a distorted tri-capped trigonal prism whereas the Eu2 2+ ion at the 6h position is located in a strongly distorted square anti-prism. The chloride ions have octahedral europium coordination (307 pm Eu-Cl).
