In the title compound, {[Co(C14H8N2O 5)(C10H8N2)]·3H 2O}n, the CoII cation is five-coordinated with a slightly distorted trigonal-bipyramidal geometry, and the 5-isonicotinamido- isophthalate ligands link CoII atoms into a layered structure. These two-dimensional arrays are further pillared by rod-like 4,4′-bipyridine ligands to give a three-dimensional framework with pcu (primitive cubic) topology. The magnetic and adsorption properties of the title compound are also discussed. ©2012 International Union of Crystallography.
