An infinite two-dimensional hybrid water–chloride network in a 4′-(furan-2-yl)-2,2′:6′,2′′-terpyridine nickel(II) matrix

Abstract

A new complex, namely bis[4′-(furan-2-yl)-2,2′:6′,2′′-terpyridine]nickel(II) dichloride decahydrate, [Ni(C19H13N3O)2]Cl2·10H2O, has been crystallized by solvent evaporation and characterized by single-crystal X-ray diffraction. The coordination environment of the NiIIcation is distorted octahedral with slight deviations from an idealized geometry. The most intriguing structural feature is an infinite two-dimensional hybrid water–chloride network parallel to (011) constructed by O—H...O and O—H...Cl hydrogen bonds involving two independent chloride ions and ten independent solvent water molecules with an L-shaped pattern. One of the furyl rings is disordered with a refined occupancy ratio of 0.786 (13):0.214 (13)
