Crystal structure of new pigments

Caption

Schematic representation of thortveitite-like structure of Zn2-xNixV2O7 (top).  Substitution of Ni for Zn produces yellow, orange and reddish hues as x value is varied (bottom).  Zinc/Nickel atoms are shown as red spheres located in a distorted five-coordinated trigonal bipyramidal environment formed by oxygen atoms (turquoise spheres). Vanadium atoms are shown as yellow spheres located in a tetrahedral arrangement formed by oxygen atoms. Image provided by Mas Subramanian, OSU College of Science.
