Abstract
Single crystals of Pb3Ni4.5Te2.5O15 have been prepared by heating pell ets of mixtures of PbO, TeO2 and nickel hydroxide carbonate to 730 deg rees C in air. X-ray investigations led to hexagonal symmetry, space g roup D-6(6)-P6(3)22, lattice constants a = 10.2589(1), c = 13.554(5), Z = 4. Typical features of the crystal structure are face sharing TeNi O9 octahedra doubles and planes of connected (TeO6)(6) and (TeO6)(3)(N iO6)(3) hexagons. The one-sided coordination of lead by oxygen is comp lemented by the lone pair of electrons. The lone pair positions are es timated by calculations of the Coulomb terms of lattice energy.
