L'oxyde double TeVO 4 II. Structure cristalline de TeVO 4-β-relations structurales
Abstract
β-TeVO 4 crystallizes in the monoclinic system with the space group {P2 1}/{c} and the parameters: a = 4.379 Å, b = 13.502 Å, c = 5.446 Å, and β = 91.72°. Vanadium occupies the center of a square pyramid of oxygens, an extra oxygen is at VO = 2.77 Å. These distorted octahedra share corners forming puckered sheets parallel to (010). The sheets are held together by [Te 2O 6] 4- groups in which tellurium is one-side coordinated by four oxygen atoms.
