Tetra-aqua-bis(3,5-di-4-pyridyl-1,2,4-triazolato-?N)cobalt(II) dihydrate.

ABSTRACT: The Co(II) atom in the title compound, [Co(C(12)H(8)N(5))(2)(H(2)O)(4)]·2H(2)O, lies on a center of inversion and is bonded to two N-heterocycles and to four water mol-ecules in a slightly distorted octahedral coordination. The coordinated and lattice water mol-ecules inter-act with the N-heterocycles through O-H?N hydrogen bonds, generating a three-dimensional supra-molecular architecture.

Crystal structure of tetra-aqua-bis(3,5-di-amino-4H-1,2,4-triazol-1-ium)cobalt(II) bis-[bis-(pyridine-2,6-di-carboxyl-ato)cobaltate(II)] dihydrate.

Project description:The asymmetric unit of the title compound, [Co(C2H6N5)2(H2O)4][Co(C7H3NO4)2]2·2H2O, features 1.5 Co(II) ions (one anionic complex and one half cationic complex) and one water mol-ecule. In the cationic complex, the Co(II) atom is located on an inversion centre and is coordinated by two triazolium cations and four water mol-ecules, adopting an octa-hedral geometry where the N atoms of the two triazolium cations occupy the axial positions and the O atoms of the four water mol-ecules the equatorial positions. The two triazole ligands are parallel offset (with a distance of 1.38 Å between their planes). In the anionic complex, the Co(II) ion is six-coordinated by two N and four O atoms of the two pyridine-2,6-di-carboxyl-ate anions, exhibiting a slightly distorted octa-hedral coordination geometry in which the mean plane of the two pyridine-2,6-di-carboxyl-ate anions are almost perpendicular to each other, making a dihedral angle of 85.87 (2)°. In the crystal, mol-ecules are linked into a three-dimensional network via C-H⋯O, C-H⋯N, O-H⋯O and N-H⋯O hydrogen bonds.

Tetra-aqua-bis(isonicotinamide-κN)cobalt(II) bis-(4-formyl-benzoate) dihydrate.

Project description:The asymmetric unit of the crystal structure of the title complex, [Co(C(6)H(6)N(2)O)(2)(H(2)O)(4)](C(8)H(5)O(3))(2)·2H(2)O, contains one-half of the complex cation with the Co(II) ion located on an inversion center, a 4-formyl-benzoate (FB) counter-anion and an uncoordinated water mol-ecule. The four O atoms in the equatorial plane around the Co(II) ion form a slightly distorted square-planar arrangement with an average Co-O bond length of 2.086 Å; the slightly distorted octa-hedral coordination is completed by the two N atoms of the isonicotinamide (INA) ligands at a slightly longer distance [2.1603 (14) Å] in the axial positions. The dihedral angle between the carboxyl-ate group and the attached benzene ring is 5.93 (13)°, while the pyridine and benzene rings are oriented at a dihedral angle of 3.09 (6)°. In the crystal structure, O-H⋯O, N-H⋯O and C-H⋯O hydrogen bonds link the mol-ecules into a three-dimensional network. π-π Contacts between the benzene and pyridine rings [centroid-centroid distance = 3.758 (1) Å] may further stabilize the crystal structure.

Bis(4-amino-3,5-di-2-pyridyl-1,2,4-triazole-κN,N)diaqua-zinc(II) dinitrate.

Project description:The asymmetric unit of the title compound, [Zn(C(12)H(10)N(6))(2)(H(2)O)(2)](NO(3))(2), contains one-half of the complex molecule and one NO(3) (-) anion. The Zn(II) ion displays a distorted tetra-gonal-pyramidal geometry with four N atoms from two chelating 4-amino-3,5-di-2-pyridyl-1,2,4-triazole (2-bpt) lig-ands in the basal plane and one water mol-ecule occupying the apical site. Another water mol-ecule at the opposite of the apical site has a weak inter-action with the Zn(II) ion [Zn-O = 2.852 (5) Å]. The Zn(II) ion and the two water mol-ecules lie on a twofold rotation axis. An extensive system of hydrogen bonds involving the NH(2) groups of the 2-bpt ligands, water mol-ecules and nitrate anions links all residues into a three-dimensional network.

Project description:In the title Co(II) complex, [Co(C(5)H(3)N(2)O(4))(2)(H(2)O)(4)]·2H(2)O, the Co(II) ion is located on an inversion center and is coordinated by two orotate (2,6-dioxo-1,2,3,6-tetrahydropyrimidine-4-carboxylate) anions and four water mol-ecules in a slightly distorted octa-hedral geometry.

In the crystal structure, inter-molecular O-H?O, N-H?O and C-H?O hydrogen bonds link the mol-ecules into a three-dimensional network. ?-? contacts between the orotate rings [centroid-centroid distances = 3.439?(2) and 3.438?(2)?Å] further stabilize the structure.

Project description:In the crystal structure of the title compound, C(12)H(10)N(6), the mol-ecules deviate slightly from planarity. The plane of the central triazole ring makes angles of 6.13 (9) and 3.28 (10)° with the pyridyl ring planes. Intra-molecular N-H⋯N inter-actions form six-membered closed rings. The crystal packing also shows weak C-H⋯π and C-H⋯N inter-actions.

catena-Poly[[[tetra-aqua-cobalt(II)]-μ-4,4'-bipyridine-κN:N'] pyridine-3,5-dicarboxyl-ate trihydrate].

Project description:The crystal structure of the title compound, {[Co(C(10)H(8)N(2))(H(2)O)(4)](C(7)H(3)NO(4))·3H(2)O}(n), consists of Co(II) polymeric complex cations, uncoordinated pyridine-3,5-dicarboxyl-ate anions and lattice water mol-ecules. The Co(II) cation is coordinated by two N atoms from two 4,4'-bipyridine ligands and four water mol-ecules in a distorted octa-hedral geometry. The 4,4'-bipyridine ligands bridge Co cations, forming a polymeric chain running along the b axis. The two pyridine rings of the 4,4'-biyridine are twisted to each other by a dihedral angle of 8.95 (9)°. Extensive O-H⋯O hydrogen bonding network is present in the crystal structure.
