摘要：

The oxygen parameters x and z of ErPO4 and ErVO4 (I 4/amd) have been refined from neutron diffraction powder data by least squares analysis. The P-O and V-O distances in the PO43- and VO43- tetrahedra are 1.54 and 1.72 angstrom respectively. The bonding mechanism in the tetrahedra is discussed.
