Tetra-aqua-(1,10-phenanthroline-5,6-dione-?N,N')cobalt(II) dinitrate.

ABSTRACT: The asymmetric unit of the title compound, [Co(C(12)H(6)N(2)O(2))(H(2)O)(4)](NO(3))(2), consists of a Co(II) complex cation with twofold rotational symmetry and two nitrate anions. The Co(II) atom has a distorted octa-hedral geometry with the basal plane occupied by two 1,10-phenanthroline-5,6-dione N atoms and two aqua O atoms, with the other two aqua ligands in axial positions. The aqua ligands are involved in extensive hydrogen bonding to nitrate and 1,10-phenanthroline-5,6-dione O atoms.

Bis[tetra-aqua-(1,10-phenanthroline-?N,N')cobalt(II)] hexa-aqua-cobalt(II) bis-[3,5-bis-(carboxyl-atometh-oxy)benzoate] tetra-hydrate.

Project description:The title compound, [Co(C(12)H(8)N(2))(H(2)O)(4)](2)[Co(H(2)O)(6)](C(11)H(7)O(8))(2)·4H(2)O, was obtanied by the reaction of cobalt acetate with 3,5-bis-(carb-oxy-meth-oxy)benzoic acid and 1,10-phenanthroline. The asymmetric unit contains one tetra-aqua-(1,10-phenanthroline)cobalt(II) cation, one half of a hexa-aqua-cobalt(II) cation that is completed by inversion symmetry, one 3,5-bis-(carboxyl-atometh-oxy)benzoate trianion and two lattice water mol-ecules. The two Co(II) atoms each show a slightly distorted octa-hedral coordination (CoO(6) and CoO(4)N(2)). The cations, anions and lattice water mol-ecules are linked by an intricate network of O-H?O hydrogen bonds into a three-dimensional structure.

Dichloridobis(1,10-phenanthroline-5,6-dione-κN,N')mercury(II).

Project description:In the title compound, [HgCl(2)(C(12)H(6)N(2)O(2))(2)], the Hg(II) atom is located on a twofold rotation axis and exists within a distorted octa-hedral geometry defined by a cis-Cl(2)N(4) donor set. Mol-ecules are connected into layers in the ac plane via extensive C-H⋯Cl contacts as each Cl atom forms two such inter-actions. Contacts between the layers are of the type C=O⋯π [O⋯centroid distance = 3.110 (8) Å].

1,10-Phenanthroline-5,6-dione ethanol monosolvate.

Project description:In the title compound, C12H6N2O2·C2H5OH, the mol-ecule of the 1,10-phenanthroline-5,6-dione is approximately planar, with a maximum deviation of 0.051?(1)?Å. In the crystal, mol-ecules are linked by O-H?N and weak C-H?O hydrogen bonds, forming supra-molecular chains propagating along [110]. ?-? stacking inter-actions are observed between the pyridine rings of neighbouring chains, the centroid-centroid separations being 3.6226?(11) and 3.7543?(11)?Å.

Tris(1,10-phenanthroline-?N,N')nickel(II) dinitrate tetra-hydrate.

Project description:In the title complex, [Ni(C(12)H(8)N(2))(3)](NO(3))(2)·4H(2)O, the Ni(II) ion is octa-hedrally coordinated by three bidentate 1,10-phenanthroline ligands, each forming a five-membered chelate ring. In the crystal, O-H?O and C-H?O hydrogen bonds are present between the complex cations, nitrate anions and water mol-ecules. O-H?O hydrogen bonds between the uncoord-inated water mol-ecules lead to the formation of a four-membered ring water cluster, with a planar configuration. There were an additional five grossly disordered water mol-ecules in the asymmetric unit, which were removed by the subroutine SQUEEZE; these were were excluded in the calculation of the molecular weight, etc. ?-? stacking inter-actions between the aromatic rings are also observed [centroid-centroid distances = 3.697?(2), 3.728?(2) and 3.761?(2)?Å].

Aqua-(hippurato)bis-(1,10-phenanthroline)cobalt(II) nitrate monohydrate.

Project description:In the title compound, [Co(C(9)H(8)NO(3))(C(12)H(8)N(2))(2)(H(2)O)]NO(3)·H(2)O, the Co(II) atom is six-coordinated by a carboxylate O atom of the hippurate (Hc) anion, a water O atom and four N atoms from two 1,10-phenanthroline ligands in a distorted octa-hedral geometry. The uncoordinated O atom of the hippuric acid anion is involved in an intra-molecular hydrogen bond to the coordinated water mol-ecule. The crystal packing is stabilized by inter-molecular O-H?O hydrogen bonds involving the Hc anions, the coordinated water mol-ecule, the nitrate anion and the uncoordinated water mol-ecule.

An acetonitrile solvatomorph of di-chlorido-(1,10-phenanthroline-5,6-dione)platinum(II).

Project description:In the title complex, [PtCl2(C12H6N2O2)]·CH3CN, the Pt(II) atom lies in a slightly distorted square-planar arrangement defined by an N2Cl2 donor set. In the packed structure, columns of complex moieties are stacked such that the neighboring units are oriented at 180° and laterally displaced with respect to each other. This prevents any overlap of the phenanthroline rings and thus there is no possibility of any π-π inter-actions between aromatic rings.

Acetato(1,10-phenanthroline-5,6-dione)silver(I) trihydrate.

Project description:In the structure of the title compound, [Ag(C(2)H(3)O(2))(C(12)H(6)N(2)O(2))]·3H(2)O, the Ag(I) atom is coordinated by both 1,10-phenanthroline-5,6-dione N atoms and one O atom from the acetate anion. The three water mol-ecules are involved in extensive hydrogen bonding to each other and to the acetate O and 1,10-phenanthroline-5,6-dione O atoms. In addition, there are weak C-H⋯O inter-actions.

Tetra-aqua-(1,10-phenanthroline-?N,N')cadmium(II) sulfate dihydrate.

Project description:In the title mononuclear complex, [Cd(C(12)H(8)N(2))(H(2)O)(4)]SO(4)·2H(2)O, the coordination geometry around the Cd(II) atom is a distorted octa-hedron, with two aqua ligands occupying the axial positions. Inter-molecular O-H?O hydrogen bonds lead to the formation of a two-dimensional layer structure parallel to (001). The layers are connected by ?-? inter-actions between the pyridyl and benzene rings of the phenanthroline ligands [centroid-centroid distances = 3.591?(1) and 3.610?(1)?Å].

A new polymorph of aqua-bis-(1,10-phenanthroline-?(2) N,N')copper(II) dinitrate.

Project description:The title mol-ecule, [Cu(C12H8N2)2(H2O)](NO3)2, is a new polymorph of a compound which up to now has been reported to crystallize space groups in C2/c and Cc. The crystal studied was twinned by non-merohedry (final BASF factor of 0.40043) with the structure being solved and refined in P-1. The Cu(II) atom is coordinated by four N atoms from two 1,10-phenanthroline ligands and an O atom from a water mol-ecule in an approximate trigonal-bipyramidal geometry. Discrete entities of one cation and two nitrate anions are formed by water-nitrate O-H?O hydrogen bonds. The components are further assembled into a three-dimensional network by C-H?O hydrogen bonds.

Diiodido(1,10-phenanthroline-5,6-dione-?N,N')mercury(II).

Project description:The Hg(II) atom in the title complex, [HgI(2)(C(12)H(6)N(2)O(2))], is tetra-hedrally coordinated by the N atoms of the chelating 1,10-phenanthroline-5,6-dione ligand and two I atoms. The range of tetra-hedral angles is broad, viz. 68.94?(17)° for the chelate angle to a wide 132.627?(15)° for the I-Hg-I angle. The ligand mol-ecule is non-planar with the O atoms lying 0.422?(5) and -0.325?(5)?Å out of the plane through the remaining atoms [r.m.s. deviation = 0.068?Å]. Mol-ecules are consolidated in the crystal packing by C-H?O inter-actions.
