Tetra-aqua-(2,2'-bipyridine-?N,N')magnesium(II) bis-(4-fluoro-benzoate).

ABSTRACT: The title compound, [Mg(C(10)H(8)N(2))(H(2)O)(4)](C(7)H(4)FO(2))(2), consists of a bivalent [Mg(C(10)H(8)N(2))(H(2)O)(4)](2+) cation and two 4-fluorbenzoate anions. In the complex cation, the Mg(II) atom is coordinated by two N atoms from a 2,2'-bipyridine ligand and four water O atoms in a distorted MgN(2)O(4) octa-hedral geometry. The Mg(II) atom is located on a twofold rotation axis and thus a cation exhibits C(2) mol-ecular symmetry. The 2,2'-bipyridine ligands exhibit nearly perfect planarity (r.m.s. deviations = 0.0061?Å). In the crystal, O-H?O and C-H?O hydrogen bonds link the cations and anions into a three-dimensional supra-molecular network.

Tetra-aqua(2,2'-bipyridine-?N,N')magnesium(II) bis-(4-bromo-benzoate).

Project description:In the complex cation of the title compound, [Mg(C(10)H(8)N(2))(H(2)O)(4)](C(7)H(4)BrO(2))(2), the Mg(II) atom is coordinated by two N atoms from a 2,2'-bipyridine ligand and four water O atoms in a distorted MgN(2)O(4) octa-hedral geometry. The cation is located on a special position on a twofold rotation axis which passes through the Mg(II) atom and the centroid of the 2,2'-bipyridine ligand. The 2,2'-bipyridine ligands exhibit nearly perfect coplanarity (r.m.s. deviation = 0.0035?Å) . In the crystal, O-H?O and C-H?O, C-H?Br hydrogen bonds and ?-? stacking inter-actions [mean inter-planar distance of 3.475?(6)?Å between adjacent 2,2'-bipyridine ligands] link the cations and anions into a three-dimensional supra-molecular network. One Br atom is disordered over two sites with occupancy factors of 0.55 and 0.45.

Tetra-aqua-bis(nicotinamide-?N)cobalt(II) bis-(2-fluoro-benzoate).

Project description:The title complex, [Co(C(6)H(6)N(2)O)(2)(H(2)O)(4)](C(7)H(4)FO(2))(2), contains one Co(II) atom (site symmetry ), two monodentate nicotin-amide (NA) ligands, four coordinated water mol-ecules and two 2-fluoro-benzoate (FB) anions. The four O atoms in the equatorial plane around the Co atom form a slightly distorted square-planar arrangement, while the slightly distorted octa-hedral coordination is completed by the two N atoms of the NA ligands in the axial positions. The dihedral angle between the carboxyl group and the adjacent benzene ring is 29.8?(3)°, while the pyridine and benzene rings are oriented at a dihedral angle of 7.97?(12)°. In the crystal structure, mol-ecules are linked by O-H?O, N-H?O and N-H?F hydrogen bonds, forming an infinite three-dimensional network. ?-? Contacts between the pyridine and benzene rings [centroid-centroid distance = 3.673?(3)?Å] may further stabilize the crystal structure.

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.

Tetra-aqua-(2,2'-bipyridine-κN,N')manganese(II) di-μ-aqua-bis-[aqua-(2,2'-bipyridine-κN,N')(5-sulfonatoisophthalato-κO)manganate(II)] tetra-hydrate.

Project description:The crystal structure of the title salt, [Mn(C(10)H(8)N(2))(H(2)O)(4)][Mn(2)(C(8)H(3)O(7)S)(2)(C(10)H(8)N(2))(2)(H(2)O)(4)]·4H(2)O, consists of mononuclear manganese(II) cations, dinuclear manganate(II) dianions and uncoordinated water mol-ecules. The dianion is located about an inversion center; the Mn(II) atom is coordinated by a 2,2'-bipyridine ligand, a sulfonatoisophthalate group, a water mol-ecule along with two bridging water mol-ecules in an octa-hedral geometry. The cation lies on a twofold rotation axis; the Mn(II) atom is coordinated by four water mol-ecules and a chelating 2,2'-bipyridine ligand in a distorted octa-hedral geometry. A partially overlapped arrangement between the bipyridine ligands and the aromatic ring of the sulfoisophthalate group of adjacent anions is observed; the distance (3.357 Å) indicates π-π stacking. Hydrogen bonds, with the water mol-ecules serving as hydrogen-bond donors, lead to a three-dimensional network architecture.

Project description:In the centrosymmetric title complex, [Ni(2)(C(14)H(8)O(4)S(2))(2)(C(10)H(8)N(2))(2)(H(2)O)(2)], the Ni(II) atom is coordinated by two N atoms from one 2,2'-bipyridine ligand, three carboxyl-ate O atoms (one bidentate and one monodentate) from two different disulfanediyldibenzoate ligands and one O atom from a coordinated water mol-ecule in an octa-hedral coordination geometry. The disulfanediyldibenzo-ate dianion bridges two Ni(II )atoms. Adjacent mol-ecules are linked through the coordinated water mol-ecules, forming a O-H?O hydrogen-bonded chain running along the a axis.

Project description:In the centrosymmetric dinuclear mol-ecule of the title compound, [Cd(2)(C(14)H(8)O(4))(2)(C(10)H(8)N(2))(2)(H(2)O)(2)], the Cd(2+) ion is coordinated by three O atoms from two different diphenyl-dicarboxyl-ate (dpa) ligands (one O,O'-bidentate and one monodentate), a chelating bipyridine ligand and a water mol-ecule, generating an extremely distorted trigonal-prismatic (or irregular) CdN(2)O(4) coordination geometry for the metal ion. The bridging ligands generate an 18-membered ring, which is stabilized by two pairs of intra-molecular O-H?O hydrogen bonds.

Tetra-aqua-(2,2'-bipyridine-?²N,N')nickel(II) sulfate.

Project description:The asymmetric unit of the title complex, [Ni(C??H?N?)(H?O)?]SO?, consists of a complex [Ni(bipy)(H?O)?]²? cation (bipy = 2,2'-bipyridine) and a non-coordinating [SO?]²? anion. The Ni(II) atom is six-coordinated in a distorted octa-hedral geometry defined by the two N atoms of the bipy ligand and four water O atoms. The crystal structure contains extensive classical O-H?O hydrogen bonds, which link the ions into a two-dimensional array in the ab plane. Layers are connected into a three-dimensional supra-molecular structure by C-H?O inter-actions.

Aqua-(2,2'-bipyridine)bis-(4-hydroxy-benzoato)zinc(II).

Project description:In the title complex, [Zn(C(7)H(5)O(3))(2)(C(10)H(8)N(2))(H(2)O)], the Zn(II) ion is coordinated by two 4-hydroxy-benzoate anions, one 2,2'-bipyridine mol-ecule and one water mol-ecule and displays a distorted octa-hedral geometry. One Zn-O bond [2.5300?(15)?Å] is much longer than the others in the mol-ecule. In the crystal structure, the face-to-face separation of 3.547?(9)?Å suggests no ?-? stacking between parallel bipyridine ring systems, and an extensive O-H?O hydrogen-bonding network between the coordinated water molecule, the phenol group and carboxylate O atoms is present.

Neighboring Co(II) atoms are linked together by two Cl bridges, forming a dinuclear Co(II) complex with inversion symmetry. There are inter-molecular O-H?Cl hydrogen bonds and inter-molecular ?-? stacking inter-actions between adjacent bpy ligands [centroid-centroid distance = 3.617?(2)?Å] in the structure.
