Sr₉La₂(WO₆)₄ containing [WO₆] octa-hedra.

ABSTRACT: A polycrystalline sample of Sr₉La₂(WO₆)₄, nona-strontium dilanthanum tetra-kis-[orthotungstate(VI)], was prepared by heating a compacted powder mixture of SrCO₃, WO₃, and La₂O₃ with an Sr:La:W molar ratio of 9:2:4 at 1473 K. X-ray crystal structure analysis was performed for a Sr₉La₂(WO₆)₄ single-crystal grain grown by reheating the sample at 1673 K. Sr₉La₂(WO₆)₄ crystallizes with four formula units in the tetra-gonal space group I4₁/a and is isotypic with Sr₁₁(ReO₆)₄. Two W sites with site symmetries of are located at the center of isolated [WO₆] o
