ABSTRACT: In the title mononuclear complex, [Ni(C(4)H(5)O(2))(2)(C(10)H(9)N(3))]·1.5H(2)O, the Ni(II) ion is in a distorted square-planar coordination environment, formed by two O atoms from two methacrylate ligands and two N atoms from a bis-chelating dipyridylamine ligand. In the crystal structure, inter-molecular O-H?O and N-H?O hydrogen bonds link complex mol-ecules and water mol-ecules into one-dimensional chains.

Project description:The Ni(II) ion in the one-dimensional title complex, {[Ni(2)(C(4)H(2)O(4))(OH)(2)(C(10)H(9)N(3))(2)]·2H(2)O}(n), has a distorted square-pyramidal coordination environment formed by three O atoms from two bridging hydroxide groups and one carboxyl-ate group of the fumarate ligand and two pyridine N atoms from a di-2-pyridylamine (dpa) ligand. Two hydroxide groups link adjacent metal centers, forming a centrosymmetric four-membered [Ni(2)(OH)(2)] ring. In the crystal structure, the H atoms of the bridging hydroxide groups form inter-molecular hydrogen bonds to both water mol-ecules. These are further linked to the uncoordinated O atoms of the carboxyl-ate groups and the NH group of a dpa ligand to generate a three-dimensional network from the chains of the coordination polymer.

catena-Poly[[[diaqua-(di-2-pyridylamine-?N,N')nickel(II)]-?-fumarato-?O:O] tetra-hydrate].

Project description:In the crystal structure of the title compound, {[Ni(C(4)H(2)O(4))(C(10)H(9)N(3))(H(2)O)(2)]·4H(2)O}(n), zigzag chains are built up from cis-[Ni(dpya)(H(2)O)(2)](2+) cations (dpya is di-2-pyridylamine) linked by bis-monodentate coordinated bridging fumarate ligands. The Ni(II) atom is coordinated by one chelating dpya ligand, two aqua ligands in trans positions and two monodentate fumarate ligands in cis positions in the form of a deformed octa-hedron. The water mol-ecules, O atoms of the fumarate carboxyl-ate groups and the amine group of the dpya ligand are involved in an extended network of intra- and inter-molecular O-H?O hydrogen bonds. Moreover, ?-? inter-actions between the pyridine rings of the dpya ligand contribute to the stability of the structure. Two of the five uncoordinated water molecules are half-occupied.

Hexa-aqua-nickel(II) bis-[tri-aqua-?3-oxalato-di-?-oxalato-bariumchromate(III)] tetra-hydrate.

Project description:The title compound, [Ni(H2O)6][BaCr(C2O4)3(H2O)3]2·4H2O, was obtained in the form of single crystals from the slow evaporation of an aqueous mixture of {Ba6(H2O)17[Cr(C2O4)3]4}·7H2O and NiSO4·6H2O in the molar ratio 1:4. Its structure is made up of corrugated anionic (101) layers of formula [BaCr(C2O4)3(H2O)3] n n - that leave voids accommodating the charge-compensating cations, [Ni(H2O)6]2+ (point group symmetry ), as well as the water mol-ecules of crystallization. The anionic layers are built from the connection of barium and chromium atoms through bridging oxalate ligands. The CrIII atom is hexa-coordinated by O atoms of three oxalate ligands while the BaII atom is tenfold coordinated by three O atoms of water mol-ecules and seven O atoms of four oxalate ligands. Each NiII atom sits on an inversion center and is coordinated by six water mol-ecules. One of the uncoordinated water mol-ecules is disordered over two sites, with a refined occupancy ratio of 0.51?(5):0.49?(5). In the crystal, extensive O-H?O hydrogen-bonding inter-actions link the anionic layers, the charge-balancing cations as well as the water mol-ecules of crystallization into a three-dimensional supra-molecular network.

Project description:The title complex, [Cu(2)(C(4)H(5)O(2))(2)(C(12)H(8)N(2))(2)(H(2)O)(2)](NO(3))(2)·2H(2)O, contains a dimeric [Cu(2)(C(4)H(5)O(2))(2)(C(12)H(8)N(2))(2)(H(2)O)(2)](2+) dication with two five-coordinated Cu(II) ions linked by two methacrylate ions in a syn-syn bridging arrangement. The dication possesses pseudo-twofold rotational symmetry. The penta-coordination of each Cu(II) ion has a distorted square-pyramidal geometry, with two N donors from a phenanthroline ligand and two carboxyl-ate O atoms occupying basal sites and the apical position being occupied by a water mol-ecule.

Bis[(1-ammonio-ethane-1,1-di-yl)diphospho-nato-?O,O']diaqua-nickel(II) nona-hydrate.

Project description:The title compound, [Ni(C(2)H(8)NO(6)P(2))(2)(H(2)O)(2)]·9H(2)O, exhibits a slightly distorted octa-hedral coordination environment around the Ni(II) atom.

The title compound contains nine partly disordered solvent water mol-ecules, which create a three-dimensional network of strong O-H?O and N-H?O hydrogen bonds.
