title: Poly[diaqua-tetra-μ-seleno-cyanato-cadmium(II)dipotassium(I)].
abstract: In the title compound, [CdK(2)(NCSe)(4)(H(2)O)(2)](n), the cadmium(II) cation is situated on a twofold rotation axis and is coordinated in a slightly distorted tetra-hedral geometry by two symmetry-related μ-1,1,1,3 and two-symmetry related μ-1,1,3,3 bridging seleno-cyanate anions, all of which are Se bonded. These bridging seleno-cyanate anions are further coordinated to two symmetry-related potassium ions. Each of the potassium ions is coordinated by one terminally bonded water mol-ecule and six seleno-cyanate anions, two of which are crystallographically independent. The asymmetric unit consists of one cadmium and one potassium cation, two bridging seleno-cyanate anions and one water mol-ecule. The polymeric subunits are further connected via the seleno-cyanate anions into a three-dimensional coordination network. In this coordination network, intramolecular hydrogen bonds between neighbouring water molecules can be found.
