(2,2'-Bipyridine-?N,N')tetra-bromidoplatinum(IV).

ABSTRACT: In the title complex, [PtBr(4)(C(10)H(8)N(2))], the Pt(IV) ion has a slightly distorted octa-hedral coordination defined by two N atoms of the chelating 2,2'-bipyridine ligand and four bromide ions. As a result of the different trans effects of the N and Br atoms, the Pt-Br bonds trans to the N atom are slightly shorter than those to mutually trans Br atoms. In the crystal structure, the mol-ecules are arranged in a V-shaped packing pattern along the b axis and stacked in columns along the a axis. In the columns, several inter-molecular ?-? inter-actions between the pyridine rings are present. The shortest ring centroid-centroid distance is 3.921?(6)?Å, with a dihedral angle of 1.6?(5)° between the ring planes. The complexes are connected by C-H?Br hydrogen bonds, forming chains along the b axis.

(5,5'-Dimethyl-2,2'-bipyridine)-iodido-trimethyl-platinum(IV).

Project description:In the title compound, [Pt(CH(3))(3)I(C(12)H(12)N(2))], the Pt(IV) atom is six-coordinated in a slightly distorted octa-hedral configuration with one CH(3) group and the I atom forming a near perpendicular axis relative to the square plane formed by the bipyridine ligand and the two remaining CH(3) groups.

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.

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.

Diaqua-bis(norfloxacinato)manganese(II) 2,2'-bipyridine solvate tetra-hydrate.

Project description:In the crystal structure of the title compound {systematic name: diaqua-bis[1-ethyl-6-fluoro-4-oxo-7-(piperazin-1-yl)-1,4-dihydro-quinoline-3-carboxyl-ato]manganese(II) 2,2'-bipyridine solvate tetra-hydrate}, [Mn(C(16)H(17)FN(3)O(3))(2)(H(2)O)(2)]·C(10)H(8)N(2)·4H(2)O, the pyridone O atom and one carboxyl-ate O atom of the two norfloxacin ligands are bound to the Mn(II) ion, which is located on an inversion centre, and occupy equatorial positions, while two aqua O atoms lie in apical positions, resulting in a distorted octa-hedral geometry. The crystal packing is stabilized by N-H?O and O-H?O hydrogen-bonding interactions.

Tris(2,2'-bipyridine-κN:N')cobalt(III) trichloride tetra-hydrate.

Project description:The title compound, [Co(C(10)H(8)N(2))(3)]Cl(3)·4H(2)O, contains discrete [Co(bpy)(3)](3+) cations (bpy is 2,2'-bipyridine), Cl(-) anions and water mol-ecules. The [Co(bpy)(3)](3+) complex cation exhibits C(2) symmetry with the twofold axis through the central Co atom and bis-ecting one bpy ligand and one of the Cl(-) anions. The four solvent water mol-ecules and the remaining two Cl(-) anions lie on a mirror plane. Hydrogen-bond inter-actions define a two-dimensional layer structure parallel to (100), which consists of seven-membered [Cl(2)(H(2)O)(5)], eight-membered [Cl(4)(H(2)O)(4)] and ten-membered [Cl(2)(H(2)O)(8)] rings.

Project description:In the title hydrate, [Pt(CH(3))(3)(CH(3)COO)(C(10)H(8)N(2))]·H(2)O, the Pt(IV) atom exhibits a distorted octa-hedral coordination geometry built up by three methyl ligands in a facial arrangement, a bipyridine ligand and a monodentately bound acetate ligand. In the crystal structure, inter-molecular O-H?O hydrogen bonds are observed between the water mol-ecule and the platinum complex, which link the mol-ecules into chains along the c axis.

Bis(2,2'-bipyridine-?N,N')dichlorido-platinum(IV) dichloride monohydrate.

Project description:In the title complex, [PtCl(2)(C(10)H(8)N(2))(2)]Cl(2)·H(2)O, the Pt(4+) ion is six-coordinated in a distorted octa-hedral environment by four N atoms from the two 2,2'-bipyridine ligands and two Cl atoms. As a result of the different trans influences of the N and Cl atoms, the Pt-N bonds trans to the Cl atom are slightly longer than those trans to the N atom. The compound displays inter-molecular hydrogen bonding between the water mol-ecule and the Cl anions. There are inter-molecular ?-? inter-actions between adjacent pyridine rings, with a centroid-centroid distance of 3.962?Å.

(2,2'-Bipyridine)(pyridine-2,6-dicarboxyl-ato)oxidovanadium(IV) ethanol monosolvate.

Project description:In the title compound, [V(C(7)H(3)NO(4))O(C(10)H(8)N(2))]·C(2)H(5)OH, the V(IV) atom exhibits a distorted octa-hedral coordination environment formed by two pyridyl N atoms of 2,2'-bipyridine (bpy), the vanadyl O atom, and two carboxyl-ate O atoms and one pyridyl N atom of the tridentate pyridine-2,6-dicarboxyl-ate (pydc(2-)) ligand. The pyridyl N atom of the pydc(2-) anion and one pyridyl N atom of bpy occupy the axial positions. O-H?O hydrogen bonds involving the ethanol solvent mol-ecule as donor and a carboxyl-ate O atom as acceptor atoms, as well as C-H?O hydrogen bonds, together with ?-? stacking inter-actions between adjacent aromatic rings (average centroid-centroid distance = 3.577?Å), seem to be effective in the stabilization of the crystal packing, resulting in the formation of a three-dimensional structure.
