New antimonate–vanadate with the rutile structure

Abstract

VCrSbO₆ has been prepared and its magnetic and electronic properties investigated. The crystal structure was refined from X-ray powder diffraction by the Rietveld method. The unit cell is tetragonal (space group P4₂/mnm, Z= 2), a= 4.5708(4)Å and c= 3.0281(3)Å. The compound is isostructural with the rutile phase FeNbO₄ and stoichiometric with respect to all three constituent metals atoms. The electron diffraction pattern is consistent with a tetragonal symmetry.
