In the crystal structure of the title compound, [Cd(NCSe)2(C7H7NO)2]n, the Cd2+ cation is coordinated by two 3-acetyl­pyridine ligands and four μ-1,3-bridging seleno­cyanate anions within a slightly distorted CdN4Se2 octa­hedron. The asymmetric units consists of one Cd2+ cation, which is situated on a center of inversion, as well as one seleno­cyanate anion and one 3-acetyl­pyridine ligand in general positions. The metal cations are μ-1,3-bridged via the seleno­cyanate anions into chains along the a axis.
