Abstract: | An Additional Oxovanadate Phase with Garnet Structure: Ca5Mg3ZnV6O24 Single crystals of Ca5Mg3ZnV6O24 were prepared by solid state reactions some degree below the melting point of the reaction mixture. It crystallizes with cubic symmetry, space group T-I4 3 d with a = 12.429 Å, Z = 4. The crystal structure is nearly related to the Garnet structure showing Ca2+ within distorted cubes (C.N. = 8) of O2? on a partly unfilled position. the octahedra position are occupied by Mg2+ and Zn2+ statistically. |
