The crystal structure of sodium orthogermanate, Na4GeO4

Abstract

The crystal structure of the title compound has been determined from single crystal X-ray diffraction data and refined toR=0.125. The unit cell is triclinic, space group P,\(\bar 1\) (No. 2),a=5.688(1),b=5.701(1),c=8.583(1) Å, α=81.32(1), β=71.50(1), γ=67.95(1)° andZ=2. The structure consists of isolated [GeO4] tetrahedra linked together by four- and five-coordinate sodium atoms. Na4GeO4 is isostructural with Na4CoO4 (which has been described to be non-centrosymmetric and for which a centrosymmetric model is presented), K4GeO4, K4SnO4 and K4PbO4.
