Poly[[(μ3-adamantane-1,3-diacetato)[μ-N-(pyridin-3-yl)isonicotinamide]nickel(II)] monohydrate], a layered coordination polymer with triangular (3,6) topology

Abstract

The title compound, {[Ni(C14H18O4)(C11H9N3O)]·H2O}n, contains octahedrally coordinated NiII ions ligated by 1,3-adamantanediacetato (ada) ligands and N-(pyridin-3-yl)isonicotinamide (3-pina) ligands, to form coordination polymer layers with a triangular (3,6) grid topology based on [Ni2(OCO)2] dimeric units. The diperiodic layer motifs stack in an ABAB pattern mediated by C—H...O supramolecular interactions between ada ligands and water molecules of crystallization to form the full triperiodic crystal structure of the title compound.
