title: Hexa-kis-(dimethyl sulfoxide-κO)calcium μ(6)-oxido-dodeca-kis-μ(2)-oxido-hexa-oxido-hexa-tungstate(VI).
abstract: In the title compound, [Ca(C(2)H(6)OS)(6)][W(6)O(19)], the cation and anion both have a crystallographically imposed centre of symmetry. The Ca(II) atom in the cation is coordinated by six O atoms from six dimethyl sulfoxide ligands in a distorted octa-hedral geometry. The [W(6)O(19)](2-) isopolyanion possesses the well-known Lindqvist structure in which each W(VI) atom is coordinated by four μ(2)-O, one terminal O and one μ(6)-O atom.
