Bis(di-2-pyridylmethane-diol-?N,O,N')nickel(II) dinitrate.

ABSTRACT: The title compound, [Ni(C(11)H(10)N(2)O(2))(2)](NO(3))(2), consists of an Ni(II) atom coordinated by two tridentate chelating di-2-pyridylmethane-diol [(2-py)(2)C(OH)(2)] ligands. The Ni(II) atom is located on an inversion center. The geometry around the Ni(II) atom is distorted octa-hedral. The gem-diol (2-py)(2)C(OH)(2) ligand adopts the coordination mode ?(1):?(1):?(1). The Ni-N and Ni-O bond lengths are typical for high-spin Ni(II) in an octa-hedral environment [Ni-N = 2.094?(2) and 2.124?(3)?Å, and Ni-O = 2.108?(3)?Å]. One of the hydr-oxy H atoms is split over two positions which both inter-act with the nitrate anion. The occurence of different O-H?O hydrogen bonds leads to the formation of a layer parallel to the (101) plane.

Bis(2,3-dimethyl-butane-2,3-diamine)nickel(II) dinitrate monohydrate.

Project description:In the title compound, [Ni(C(6)H(16)N(2))(2)](NO(3))(2)·H(2)O, the bis-(2,3-dimethyl-butane-2,3-diamine)nickel(II) complex cation possesses a relatively undistorted square-planar geometry about the Ni atom, which lies on an inversion centre and is coordinated by four N atoms from two symmetry-related 2,3-diamino-2,3-dimethyl-butane (tmen) ligands. The amine groups are N-H?O hydrogen bonded to the nitrate anions, which are, in turn, linked by inter-stitial water mol-ecules lying on a twofold axis. The infinite zigzag chains thus formed along [001] are further connected to each other by N-H?O hydrogen bonds towards the water mol-ecules, forming layers of two-dimensional hydrogen-bonded arrays.

Di-?-bromido-bis-[bromido(di-2-pyridylmethane-diol-?N,N')copper(II)] dihydrate.

Project description:The centrosymmetric title complex, [Cu(2)Br(4)(C(11)H(10)N(2)O(2))(2)]·2H(2)O, was one of three complexes isolated by slow evaporation of an acetonitrile reaction mixture of CuBr(2) with di-2-pyridyl ketone (1:1 molar ratio). The title complex contains a 1:1 metal-to-ligand ratio of copper(II) with the hydrated form of the ligand di-2-pyridylmethane-diol. The copper centers are bridged by bromide donors, leading to a Cu-Cu distance of 4.090?(6)?Å. The crystals form as non-merohedral twins with two components related by a 180° rotation around the normal to [100]; the selected sample had a twin ratio of 0.63:0.37.

Di-?-methacrylato-?O:O'-bis-[aqua-bis(1,10-phenanthroline-?N,N')copper(II)] dinitrate dihydrate.

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. In the crystal packing, mol-ecules are linked to form a three-dimensional framework by O-H?O and C-H?O hydrogen bonds and ?-? inter-actions [centroid-centroid distances of 3.6039?(15), 3.5301?(15), 3.6015?(15), 3.6496?(15) and 3.6858?(15)?Å].

Di-?-azido-?N:N-bis-{aqua-[bis-(1H-benzimidazol-2-ylmeth-yl)amine]-copper(II)} dinitrate.

Project description:In the centrosymmetric dinuclear title complex, [Cu(2)(N(3))(2)(C(16)H(15)N(5))(2)(H(2)O)(2)](NO(3))(2), the Cu(II) ion is in a distorted octa-hedral coordination environment with long axial Cu-N(azide) [2.821?(6)?Å] and Cu-O(water) [2.747?(5)?Å] bonds as a result of the Jahn-Teller effect. Two symmetry-related azide ligands bridge in ?(2)-modes giving a Cu?Cu distance of 3.533?(2)?Å. In the crystal, N-H?O and O-H?O hydrogen bonds link the components into a three-dimensional network. In addition, there are weak inter-molecular C-H?N hydrogen bonds and ?-? stacking inter-actions with centroid-centroid distances ranging from 3.562?(2) to 3.974?(2)?Å.

Bis(di-2-pyridylmethane-diol-?N,O,N')copper(II) bis-(tetra-fluorido-borate) dihydrate.

Project description:The title complex, [Cu(C(11)H(10)N(2)O(2))(2)](BF(4))(2)·2H(2)O, was isolated as a dihydrate from a 1:2 molar mixture of copper(II) tetra-fluoridoborate hexa-hydrate with di-2-pyridyl ketone in aqueous solution. The centrosymmetric complex cation is structurally similar to that found in previously reported salts and exhibits Cu-O bonds deviating by 25 degrees from an octa-hedral geometry by the so-called 'off-axis angle' distortion. The BF(4) (-) anion exhibits a two site disorder of the fluorine atoms [ratio 0.210?(8):0.790?(8)].

Di-aqua-bis-(nicotinamide-?N (1))bis-(thio-cyanato-?N)nickel(II).

Project description:In the title complex, [Ni(NCS)2(C6H6N2O)2(H2O)2], the Ni(II) ion is located on an inversion center and is coordinated in a distorted octa-hedral environment by two N atoms from two nicotinamide ligands and two water mol-ecules in the equatorial plane, and two N atoms from two thio-cyanate anions in the axial positions, all acting as monodentate ligands. In the crystal, weak N-H?S hydrogen bonds between the amino groups and the thio-cyanate anions form an R 4 (2)(8) motif. The complex mol-ecules are linked by O-H?O, O-H?S, and N-H?S hydrogen bonds into a three-dimensional supra-molecular structure. Weak ?-? inter-actions between the pyridine rings is also found [centroid-centroid distance = 3.8578?(14)?Å].

Bis[tris(propane-1,3-diamine-?(2) N,N')-nickel(II)] di-aqua-bis(propane-1,3-di-amine-?(2) N,N')nickel(II) hexa-bromide dihydrate.

Project description:In the title compound, [Ni(C3H10N2)3]2[Ni(C3H10N2)2(H2O)2]Br6·2H2O, one Ni(2+) cation, located on an inversion centre, is coordinated by four N atoms from two ligands and by two water O atoms. The other Ni(2+) cation, located in a general position, is coordinated by six N atoms from three ligands. In both cases, the Ni(2+) cation has an octa-hedral coordination environment. The overall structural cohesion is ensured by three types of hydrogen bonds, N-H?Br, O-H?Br and O-H?O, which connect the two types of complex cations, the bromide counter-anions and the lattice water molecules into a three-dimensional network.
