ChemInform Abstract: 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.
