The asymmetric unit of the title compound, [Co2(NCS)4(C10H8N2)3(C2H6OS)2]n, consists of one CoII atom, two thiocyanate anions, one dimethyl sulfoxide molecule and one and a half 4,4′-bipyridine molecules. The half-molecule is completed by inversion symmetry. The CoII atom is coordinated in a distorted octahedral geometry by two N atoms from two thiocyanate anions, one O atom from dimethyl sulfoxide as a terminal ligand and three N atoms from three 4,4′-bipyridine molecules as bridging ligands linking the cations, with a CoCo separation of 11.5964 (5) Å. This generates a two-dimensional structure parallel to (-103). A C—HS hydrogen bond links the layers into a three-dimensional supramolecular framework. The layers are stacked in an ABC fashion preventing the occurrence of interlayer void space and hence leading to the absence of lattice solvent and/or organic guest molecules in the structure.
