An oxotantalate with network-type structure: Cs3Ta5O14

  • 1. Giessen Univ. (Germany, F.R.)

Description

Cs3Ta5O14 was obtained for the first time as colourless single crystals, orthorhombic, a = 26.235(2), b = 7.429(1), c = 7.388(1) A, Z = 4, space group Pbam. According to four-circle-diffractometer data (1521 hkl, F0 > 1.5 σ(F0), 30 <= THETA <= 300, R = 10%) it crystallizes with a complicated network-type structure. Ta is partly in an octahedral (C.N.6), partly in a trigonal-bipyramidal (C.N.5) environment. The [Ta5O14] network contains channels occupied by Cs. Effective Coordination Numbers, ECoN, and the Madelung Part of the Lattice Energy, MAPLE, have been calculated and are discussed. (author)
