Sr{sub 9}Ni{sub 6.64}O{sub 21}: A new member (n = 2) of the perovskite-related A{sub 3n+3}A{sub n}{prime}B{sub 3+n}O{sub 9+6n} family

Crystals of a new phase Sr{sub 9}Ni{sub 6.64}O{sub 21} were grown. This compound in the n = 2 member of the A{sub 3n+3}A{sub n}{prime}B{sub n+3}O{sub 6n+9} series. The composition and the crystal structure have been established form X-ray single crystal diffraction data. The structure contains face-shared chains of NiO{sub 6} polyhedra parallel to the c axis and is related with hexagonal 2H polytype perovskite. Sr{sub 9}Ni{sub 6.64}O{sub 21} crystallizes in the space group R3c (No. 167) with a = 9.467(2) {angstrom}, c = 35.87(5) {angstrom}, V = 2784.(4) {angstrom}{sup 3}, and Z = 6. A comparison is made between the structure of the title compound and the other members of the series.
