摘要
Single crystals of (Cu, Zn)4AlTaO8 were prepared by solid state reaction at 1300-degrees-C. X-ray investigations showed hexagonal symmetry, space group C-6v(4)-P6(3)mc; a = 5.994 angstrom; c = 9.954 angstrom; Z = 2. There is a statistical distribution of Zn2+ and Cu2+ ions, and of Cu2+ and Al3+ ions, coordinated respectively by six or four O2- ions forming octahedra or tetrahedra. A three-dimensional network of [(Cu, Zn)4AlO8]5- ions encloses isolated octahedrally coordinated Ta5+ ions. The crystal structure is of the low temperature LiFeSnO4 type.
