摘要: Abstract Ba 6 Zn 7 F 26 is monoclinic (S.G. C 2/ m ): a = 19.46(1) A˚, b 5.956(2) c 12.243(5) β 128.88(1)°, Z 2. The structure has been refined from 1730 independent reflections to R 0.046 ( ω 0.049). three dimensional network can be described as layers containing intergrown rutile and perovskite units. Two are connected by isolated octahedra. An alternative description uses defective blocks joined comparison with the 2 Ni 3 10 suggests “condensation” mechanism which could explain progressive transformation related structures structure. All 2+ (three (4 i ) sites), form dense packing − . They dodeca-coordinated, hcp fcc type for (Ba 1 /Ba ), respectively.
