Tetra-aqua-bis-(pyridine-3-carbo-nitrile-?N ¹)nickel(II) benzene-1,4-di-carboxyl-ate tetra-hydrate.

ABSTRACT: A nickel(II) terephthalate complex, viz. [Ni(C₆H₄N₂)₂(H₂O)₄](O₂CC₆H₄CO₂)·4H₂O, has been synthesized and studied by single-crystal X-ray diffraction. It crystallizes in the triclinic space group P . The crystal structure shows an approximately octa-hedral coordination environment of the complex with the [Ni(H₂O)₄(3-NCpy)₂]²⁺ (3-NCpy is pyridine-3-carbo-nitrile) cation associated with four free water mol-ecules and hydrogen bonded to a terephthalate dianion [graph set R ² ₂(8)]. The supra-molecular structure of the compound is stabilized by a three-dimensional array of O-H?O and O-H?N hydrogen bonds, along with ?-? stacked pyridine-3-carbo-nitrile rings and C-H?O inter-actions.

Project description:The title organic salt, 6C(3)H(10)N(+)·C(10)H(2)O(8) (4-)·C(10)H(4)O(8) (2-)·4H(2)O, contains seven independent entities in the asymmetric unit which comprises three propyl-ammonium cations, two water mol-ecules, half a 2,5-dicarb-oxy-benzene-1,4-carboxyl-ate dianion (H(2)btc(2-)) and half a benzene-1,2,4,5-tetra-carboxyl-ate tetra-anion (btc(4-)), the latter two anions being located about centres of inversion. One of the water mol-ecules is disordered over two positions in a 0.55 (2):0.45 (2) ratio. The combination of mol-ecular ions and water mol-ecules results in an extensive and complex three-dimensional network of hydrogen bonds, the network being made up of nine unique N-H⋯O inter-actions between the ammonium cations and the anions, as well as four unique O-H⋯O inter-actions between the water mol-ecules and the anions.

Project description:In the title compound, {[Zn(C(10)H(8)N(2))(H(2)O)(4)](C(8)H(4)O(4))}(n), the Zn(II) atoms, lying on a twofold rotation axis, are bridged by 4,4'-bipyridine ligands, resulting in a linear chain along the b axis. In the chain, the Zn(II) atom adopts a slightly distorted octa-hedral coordination geometry involving four water mol-ecules at the equatorial positions. The noncoordinated benzene-1,4-dicarboxyl-ate anion, which is also located on a twofold rotation axis, bridges adjacent chains through O-H?O hydrogen bonds, forming a three-dimensional supra-molecular network.

One presents a trigonal-bipyramidal coordination geometry defined by five O atoms [three from two carboxyl-ate groups of two benzene-1,3,5-tricarboxyl-ate (BTC) ligands and the other two deriving from three water mol-ecules], while the other lies on an inversion centre and exists in a slightly distorted octa-hedral coordination geometry defined by six O atoms (two from two carboxyl-ate groups of two BTC ligands and the others from four water mol-ecules). A three-dimensional framework is further strengthened via O-H?O hydrogen-bonding inter-actons.
