摘要：

Single crystals of Sr12Ni7.5O27 were prepared in closed silver tubes using a KO2 flux. X-ray investigations show trigonal symmetry, space group D3(2)-P321, a = 9.474 angstrom, c = 7.802 angstrom, Z = 1. It belongs to the modified perovskites, characterized by face-shared NiO9 double octahedra and underoccupied trigonal NiO6 prisms. The oxidation state of the nickel ions can be verified by calculations of the Coulomb terms of the lattice energy.
