Abstract

In the title compound, [Co(NCS)2(C16H16N4O2)]n, the octa­hedrally coordinated CoII ion lies on a crystallographic inversion center, with trans isothio­cyanate ligands. Pyridyl N-donor atoms and formyl O-donor atoms from exotetra­dentate bis­(4-pyridyl­carbon­yl)piperazine (4-bpfp) ligands link the Co(NCS)2 units into a [Co(NCS)2(4-bpfp)]n coordination polymer layer that is oriented parallel to (101). The layers stack along [010] to construct the pseudo-three-dimensional structure.
