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

ABSTRACT: 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(di-2-pyridyl-amine-?N,N')bis-(thio-cyanato-?N)nickel(II).

Project description:The mononuclear neutral title complex, [Ni(NCS)(2)(C(10)H(9)N(3))(2)], shows a cis-octa-hedral geometry around the Ni(II) ion, formed by two chelating di-2-pyridyl-amine (Hdpa) ligands and two thio-cyanate anions. Both amine H atoms are involved in N-H?S hydrogen bonding, resulting in the formation of layers of inter-linked mol-ecules parallel to the ab plane, which are further held together by weak ?-? inter-actions between adjacent complexes, involving one ring of each dipyridyl-amine unit [centroid-centroid distance = 3.777?(4)?Å], forming a three-dimensional assembly.

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

Crystal structure of di-aqua-bis-(2,6-di-methyl-pyrazine-?N)bis-(thio-cyanato-?N)cobalt(II) 2,5-di-methyl-pyrazine tris-olvate.

Project description:In the crystal structure of the title compound, [Co(NCS)2(C6H8N2)2(H2O)2]·3C6H8N2, the Co(II) cation is coordinated by two terminally N-bound thio-cyanate anions, two water mol-ecules and two 2,6-di-methyl-pyrazine ligands, forming a discrete complex with a slightly distorted octa-hedral N4O2 coordination environment. The asymmetric unit contains one Co(II) cation and three halves of 2,5-di-methyl-pyrazine solvate mol-ecules, all entities being completed by inversion symmetry, as well as one thio-cyanate anion, an aqua ligand and a 2,6-di-methyl-pyrazine ligand, all in general positions. In the crystal, discrete complexes are arranged in a way that cavities are formed where the noncoordinating 2,5-di-methyl-pyrazine mol-ecules are located. The coordination of the latter to the metal is prevented due to the bulky methyl groups in vicinal positions to the N atoms, leading to a preferential coordination through the 2,6-di-methyl-pyrazine ligands. The complex mol-ecules are linked by O-H?N hydrogen bonds between the water H atoms and the N atoms of 2,5-di-methyl-pyrazine solvent mol-ecules, leading to a layered structure extending parallel to (100).

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.
