Abstract

Refinements of the crystallographic structures of SmVO₄, EuVO₄, GdVO₄ and DyVO₄ have been carried out by means of three-dimensional single-crystal X-ray diffractometry. These orthovanadate compounds crystallize in the tetragonal space group I4¹/ amd (Z=4) with respective lattice constants of a=7.2647(9), 7.2358(7), 7.2122(7), 7.1429(8) Å and c=6.384(1), 6.362(1), 6.346(2), 6.300(2) Å. Anisotropic refinements of the structural data using a full-matrix least-squares program yielded final reliability (R) factors of 0.026, 0.049, 0.042 and 0.041 based on 266, 273, 261 and 220 unique reflections for Ln=Sm, Eu, Gd and Dy, respectively. The lanthanide (Ln) atoms are eight-coordinated to oxygen atoms with two unique Ln-O bond lengths. These non-equivaient vertices form two bisphenoidal sets. A distorted triangulated dodecahedron is produced by connecting the oxygen vertices. The orthovanadate group in each compound is a distorted tetrahedron. Important crystal data, parameters, bond lengths and angles are tabulated.
