Abstract
PbV2O6 crystallizes in the orthorhombic space group Pnma with a = 9.771(10), b = 3.684(4), c = 12.713(13) Å, and Z = 4. The structure was determined using 816 reflections measured with an automatic diffractometer and refined by full-matrix least squares to an R value of 0.052. The two unique vanadium ions lie on mirror planes and are each coordinated to five oxygen atoms lying between 1.61 and 2.06 Å. The distorted octahedra are completed by a sixth V–O interaction which is 2.73 Å for V(1) and is 2.57 Å for V(2). The lead ion is coordinated to nine oxygen atoms lying in a spherical shell with inner and outer radii of 2.56 and 2.90 Å. The structure consists of chains of VO6 octahedra paralleling the b axis.Keywords
