A quaternary germanium(II) phosphate, Na[Ge₄(PO₄)₃]

C.-S. Lee and S.-F. Weng

Abstract: A new germanium(II) phosphate, sodium tetragermanium tris(phosphate), Na[Ge₄(PO₄)₃], has been synthesized by a solid-state reaction. The compound is isotypic with A[Sn₄(PO₄)₃] (A = Na, K, NH₄). It features a [Ge₄(PO₄)₃]^- framework made up of GeO₃ pyramids and PO₄ tetrahedra, which are linked by shared corners, yielding a three-dimensional structure. The crystal studied showed partial inversion twinning.
