catena-Poly[[bis-(3-acetyl-pyridine-κN)cadmium]-di-μ-seleno-cyanato-κ(2)N:Se;κ(2)Se:N]

In the crystal structure of the title compound, [Cd(NCSe)(2)(C(7)H(7)NO)(2)](n), the Cd(2+) cation is coordinated by two 3-acetyl-pyridine ligands and four μ-1,3-bridging seleno-cyanate anions within a slightly distorted CdN(4)Se(2) octa-hedron. The asymmetric units consists of one Cd(2+) cation, which is situated on a center of inversion, as well as one seleno-cyanate anion and one 3-acetyl-pyridine ligand in general positions. The metal cations are μ-1,3-bridged via the seleno-cyanate anions into chains along the a axis.
