Abstract

Single crystals of Pb3Ni4.5Te2.5O15 have been prepared by heating pellets of mixtures of PbO, TeO2 and nickel hydroxide carbonate to 730 °C in air. X-ray investigations led to hexagonal symmetry, space group d66-P6322, lattice constants a = 10.2589(1), c = 13.554(5), Z = 4. Typical features of the crystal structure are face sharing TeNiO9 octahedra doubles and planes of connected (TeO6)6 and (TeO6)3(NiO6)3 hexagons. The one-sided coordination of lead by oxygen is complemented by the lone pair of electrons. The lone pair positions are estimated by calculations of the Coulomb terms of lattice energy.
