Cis-Bis(azido-?N)bis-(pyridine-2-carbox-amide-?N,O)nickel(II).

ABSTRACT: The title compound, [Ni(N(3))(2)(C(6)H(6)N(2)O)(2)], was obtained as the first crystalline product from the reaction of Ni(NO(3))(2)·6H(2)O, picolinamide and NaN(3) in aqueous media. After a few days in the mother liquor, crystals of the cis isomer transformed into the trans isomer [?akovi? & Popovi? (2007 ?). Acta Cryst. C63, m507-m509]. The Ni atom exhibits a distorted octa-hedral environment and contains two azide ions and two planar N,O-chelating picolinamide ligands, all cis related. The dihedral angle between the two chelate rings is 82.43?(7)°. Pairs of mol-ecules are linked by N-H?N hydrogen bonds into cyclic R(2) (2)(16) dimers, which are further packed into a three-dimensional framework by C(6) and C(8) chains by N-H?N hydrogen bonds.

Crystal structures of tetra-kis-(pyridine-4-thio-amide-κN)bis-(thio-cyanato-κN)cobalt(II) monohydrate and bis-(pyridine-4-thio-amide-κN)bis-(thio-cyanato-κN)zinc(II).

Project description:Reaction of Co(NCS)2 and Zn(NCS)2 with 4-pyridine-thio-amide led to the formation of compounds with composition [Co(NCS)2(C6H6N2S)4]·H2O (1) and [Zn(NCS)2(C6H6N2S)2] (2), respectively. The asymmetric unit of compound 1, consists of one cobalt(II) cation, two thio-cyanate anions, four 4-pyridine-thio-amide ligands and one water mol-ecule whereas that of compound 2 comprises one zinc(II) cation that is located on a twofold rotation axis as well as one thio-cyanate anion and one 4-pyridine-thio-amide ligand in general positions. In the structure of compound 1, the cobalt(II) cations are octa-hedrally coordinated by two terminal N-bonding thio-cyanate anions and by the N atoms of four 4-pyridine-thio-amide ligands, resulting in discrete and slightly distorted octa-hedral complexes. These complexes are linked into a three-dimensional network via inter-molecular N-H⋯S hydrogen bonding between the amino H atoms and the thio-cyanate S atoms. From this arrangement, channels are formed in which the water mol-ecules are embedded and linked to the host structure by inter-molecular O-H⋯S and N-H⋯O hydrogen bonding. In the structure of compound 2, the zinc(II) cations are tetra-hedrally coordinated by two N-bonding thio-cyanate anions and the N atoms of two 4-pyridine-thio-amide ligands into discrete complexes. These complexes are likewise connected into a three-dimensional network by inter-molecular N-H⋯S hydrogen bonding between the amino H atoms and the thio-amide S atoms.

Project description:In the crystal structure of the title compound, [HgBr(2)(C(5)H(5)N(3)O)(2)](n), the Hg(II) cation is located on an inversion center and is coordinated by two N atoms from the pyrazine rings and four bridging Br(-) anions in a distorted octa-hedral geometry. The Br(-) anions bridge the Hg(II) cations with significantly different Hg-Br bond distances of 2.4775 (8) and 3.1122 (8) Å, forming polymeric chains running along the a axis. Inter-molecular N-H⋯O and N-H⋯N hydrogen bonds are effective in the stabilization of the crystal structure.

Tetra-aqua-bis(pyridine-3-sulfonato-κN)nickel(II).

Project description:In the mol-ecule of the title compound, [Ni(C(5)H(4)NO(3)S)(2)(H(2)O)(4)], the Ni(II) cation is located on an inversion center and is coordinated by four water mol-ecules and two pyridine-3-sulfonate anions with an NiN(2)O(4) distorted octa-hedral geometry. The face-to-face separation of 3.561 (5) Å between parallel pyridine rings indicates the existence of weak π-π stacking between the pyridine rings. The structure also contains inter-molecular O-H⋯O hydrogen bonding and weak C-H⋯O hydrogen bonding.

Aqua-bis(4-methyl-benzoato)-κO;κO,O'-bis-(pyridine-κN)nickel(II).

Project description:In the title mononuclear complex, [Ni(C(8)H(7)O(2))(2)(C(5)H(5)N)(2)(H(2)O)], the Ni(II) atom is in a distorted octa-hedral arrangement, coordinated by three carboxylate O atoms from one bidentate 4-methyl-benzoate ligand and one monodentate 4-methyl-benzoate ligand, two N atoms from pyridine ligands, axially positioned, and a water mol-ecule. The equatorially positioned water mol-ecule and uncoordinated carb-oxylate O atom form an intra-molecular hydrogen bond. An inter-molecular O-H⋯O hydrogen bond between the coordinated water mol-ecule and carboxylate O atom of the 4-methyl-benzoate ligand forms infinite chains along the b axis. These chains are connected by C-H⋯π inter-actions.

Bis[2-(benzyl-amino)-pyridine-κN]bis-(2-formyl-phenolato-κO,O')nickel(II).

Project description:In the title complex, [Ni(C(7)H(5)O(2))(2)(C(12)H(12)N(2))(2)], the Ni(II) atom lies on a center of inversion and is coordinated in an octa-hedral geometry by two 2-(benzyl-amino)-pyridine (2-BAP) and two 2-formyl-phenolate ligands with the O-atom donors in the equatorial plane and the pyridine N atoms in axial positions. There are hydrogen-bonding inter-actions between the secondary amine H atom and the phenolate O atom, as well as C-H⋯O inter-actions, which result in the dihedral angle between the aromatic phenyl ring of the 2-formyl-phenolate moiety and the pyridine ring being 80.23 (4)°. In the packing, there are both C-H⋯π inter-actions, which link the mol-ecules into chains along the b axis, and offset π-π inter-actions involving both the pyridine and phenyl rings of the 2-BAP ligands [centroid-centroid distances = 4.0100 (8) Å for the pyridine rings and 3.6601 (8) and 4.8561 (8) Å for the phenyl rings].
