Abstract: | The crystal structure of the compound Li3Zn0.5GeO4 has been determined and refined by means of three-dimensionalFourier syntheses and least squares. Li3Zn0.5GeO4 crystallizes orthorhombic with space groupD

-Pmnb (No. 62) and the lattice parametersa=6.29,b=10.74 andc=5.17 Å. The crystal structure consists of isolated GeO4] tetrahedra, which are linked together by (Li,Zn)O4] tetrahedra analogous to Li3PO4(h). An additional eight-fold position is partly occupied by two lithium atoms. The occupancy of this position may vary according to the observed range of composition, which lies between Li3.8Zn0.1GeO4 and Li2.6Zn0.7GeO4. |
