Description / Table of Contents:
ZnTa2O6, a New Member of tri-α-PbO2-Type (with Supplement Data about ZnNb2O6)For the first time single crystals of ZnTa2O6 were prepared and investigated by single crystal X-ray work. a = 4.702, b = 17.094, c = 5.070 Å, space group D2h14-Pbcn. ZnTa2O6 shows [MO6]-octahedra-chains with a typical metal distribution. 2/3 of these chains contain alternating Zn2+- and Ta5+-ions. For that reason ZnTa2O6 does not belong to the Columbitstructure but to the tri-α-PbO2-type.
Notes:
Erstmals wurden Einkristalle von ZnTa2O6 dargestellt und mit Diffraktometermessungen die Kristallstruktur bestimmt. a = 4,702, b = 17,094, c = 5,070 Å, Raumgruppe D2h14-Pbcn, 4 Formeleinheiten je Elementarzelle. nT a2O6 besitzt Oktaederketten die teilweise alternierend mit Zn2+ oder Ta5+ besetzt sind. Somit gehört es zur tri-α-PbO2-Struktur.
