Abstract
The title compound, Cs5[PNi(H2O)W11O39]·2H2O, is tetragonal with space groupP42/ncm and cell dimensionsa=20.908(5),c=10.391(6) Å. The single-crystal structure determination (diffractometer data, Mo radiation,R=0.054 for 1484 unique reflexions) shows that two types of disorder are present: the Ni atom substituting for W in the parentα-PW12O 3−40 anion is distributed equally over all twelve W sites and, in addition, the anion lies at a crystal site of symmetry 2/m in two equally weighted orientations related by the two-fold axis. The dimensions of the anion are normal.
