A Tricapped Trigonal Prismatic EuO(H₂O)₈ Site in Trihydrogen Tris(octaaquaeuropium) Dipotassium Digermanohexatitanooctadecatungstate(14-) Tridecahydrate

This paper reports the first observation of a tricapped trigonal prismatic EuO(H₂O)₈ site containing one anion O and eight aqua O atoms in K₂[Eu(H₂O)₈]₃H₃[(GeTi₃W₉O₃₇)₂O₃].13H₂O. Each half of the [(GeTi₃W₉O₃₇)₂O₃]^14- anion, which exhibits almost the same structure as the anion in K₉H₅[(GeTi₃W₉O₃₇)₂O₃]. 16H₂O, is coordinated by either three Eu³⁺ or two K⁺ atoms.
