Di-aqua-bis-[N-(2-fluoro-benz-yl)-N-nitroso-hydroxy-laminato-?(2) O,O']nickel(II).

ABSTRACT: In the centrosymmetric title compound, [Ni(C7H6FN2O2)2(H2O)2], the Ni(II) cation is in a slightly distorted octa-hedral environment and is surrounded by four O atoms from the N-O groups of the organic ligands [Ni-O = 2.0179?(13) and 2.0283?(12)?Å], and two water mol-ecules [Ni-O = 2.0967?(14)?Å]. The N-(2-fluoro-benz-yl)-N-nitroso-hydroxy-laminate monoanions act as bidentate chelating ligands. In the crystal, the Ni cations in the columns are shifted in such a way that the coordinated water mol-ecules are involved in the formation of hydrogen bonds with the O atoms of the organic species of neighbouring mol-ecules. Thus, a two-dimensional network parallel to (100) is built up by hydrogen-bonded molecules.

Project description:In the centrosymmetric title compound, [Cu(C5H11N2O2)2], the Cu(2+) ion, located on an inversion centre (Wyckoff position 2b), is in a square-planar environment, surounded by four O atoms of the N-O groups of two N-nitroso-N-pentyl-hydroxy-laminate ligands [Cu-O = 1.9042 (17) and 1.9095 (16) Å]. The hy-droxy-laminate monoanions are bidentate chelating ligands. The Cu(2+) cations form stacks along [010], with inter-molecular Cu⋯N contacts of 3.146 (2) and 3.653 (2) Å.

The geometry of both five-coordinate Pb(II)atoms is distorted Ψ-octa-hedral; if another two longer inter-molecular Pb⋯O inter-actions [at 2.955 (1) and 3.099 (1) Å] are considered, the geometry is a distorted Ψ-square anti-prism.

The geometries of the five-coordinate Pb(II) atoms in the two independent mol-ecules are ?-octa-hedral; if more remote Pb?O inter-actions are also considered, the coordination number is increased to six for one mol-ecule and to seven for the other. Their coordination polyhedra are ill defined in the chain motif, which runs along [100].

Crystal structure of di-aqua-bis-(2-chloro-pyridine-κ<i>N</i>)bis-(thio-cyanato-κ<i>N</i>)nickel(II).

Project description:The asymmetric unit of the title compound, [Ni(NCS)2(C5H4ClN)2(H2O)2], consists of one nickel(II) cation that is located on a center of inversion and one thio-cyanate anion, one water mol-ecule and one 2-chloro-pyridine ligand all occupying general positions. The NiII cation is octa-hedrally coordinated by two terminal N-bound thio-cyanato ligands, two aqua ligands and two N-bound 2-chloro-pyridine ligands into discrete complexes. Individual complexes are linked by inter-molecular O-H⋯S and O-H⋯Cl hydrogen-bonding inter-actions into a layered network extending parallel to the bc plane. Weak inter-actions of types C-H⋯S and C-H⋯Cl consolidate the crystal packing.

Tetra-aqua-bis(nicotinamide-κN)nickel(II) bis-(2-fluoro-benzoate).

Project description:The asymmetric unit of the title complex, [Ni(C(6)H(6)N(2)O)(2)(H(2)O)(4)](C(7)H(4)FO(2))(2), contains one-half of the complex cation with the Ni(II) atom located on an inversion center, and a 2-fluoro-benzoate (FB) counter-anion. The four O atoms in the equatorial plane around the Ni atom form a slightly distorted square-planar arrangement with an average Ni-O bond length of 2.079 Å, and the slightly distorted octa-hedral coordination is completed by the two N atoms of the nicotinamide (NA) ligands in the axial positions. The dihedral angle between the carboxyl group and the attached benzene ring is 28.28 (11)°, while the pyridine and benzene rings are oriented at a dihedral angle of 8.31 (4)°. In the crystal structure, O-H⋯O, N-H⋯O, C-H⋯O, and C-H⋯F hydrogen bonds link the mol-ecules into a three-dimensional network. π-π Contacts between the pyridine and benzene rings [centroid-centroid distance = 3.626 (1) Å] may further stabilize the crystal structure. The 2-fluoro-benzoate anion is disordered over two orientations, with an occupancy ratio of 0.85:0.15.

Bis{?-N-[(E)-4-benz-yloxy-2-oxidobenzyl-idene]-4-nitro-benzene-carbo-hydrazidato}bis-[di-aqua-nickel(II)] di-methyl-formamide tetra-solvate.

Project description:The molecule of the title complex, [Ni2(C21H15N3O5)2(H2O)4]·4C3H7NO, is located on an inversion centre. This results in a dimeric Ni(II) complex, with the two Ni(II) atoms bridged by phenolate O atoms. The tridentate ligand is chelated to each Ni(II) atom via one N and two O atoms of the imino-late form of the hydrazide moiety, which has the same conformation as the free ligand. The coordination geometry around each Ni(II) ion is slightly distorted octa-hedral. A supra-molecular three-dimensional architecture is created by dominant inter-molecular O-H?N, O-H?O and C-H?O hydrogen-bonding inter-actions. These are augmented by two C-H?? inter-actions and a ?-? inter-action with a centroid-centroid distance of 3.681?(2)?Å.

Di-aqua-bis-(cinnamato-κ(2) O,O')cadmium.

Project description:The title complex, [Cd(C9H7O2)2(H2O)2], was obtained as an unintended product of the reaction of cadmium nitrate with hexa-methyl-ene-tetra-mine and cinnamic acid. The Cd(II) ion lies on a twofold rotation axis and is coordinated in a slightly distorted trigonal-prismatic environment. In the crystal, the V-shaped mol-ecules are arranged in an inter-locking fashion along [010] and O-H⋯O hydrogen bonds link the mol-ecules, forming a two-dimensional network parallel to (001).

Bis(2,6-di-methyl-anilinium) di-aqua-bis-(di-hydrogen diphosphato-κ(2) O,O')cobaltate(II).

Project description:In the title compound, (C8H12N)2[Co(H2P2O7)2(H2O)2], the Co(2+) ion lies on a crystallographic inversion centre and adopts a slightly distorted octa-hedral CoO6 coordination geometry arising from two chelating diphosphate [H2P2O7](2-) ligands and two trans water mol-ecules. In the crystal, the components are linked by O-H⋯O, N-H⋯O and C-H⋯O hydrogen bonds and weak aromatic π-π stacking [shortest centroid-centroid separation = 3.778 (2) Å] inter-actions. (001) layers of alternating organic cations and complex inorganic anions are apparent.

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].
