Bis(azido-?N)(1,10-phenanthroline-?N,N')palladium(II).

ABSTRACT: In the title complex, [Pd(N(3))(2)(C(12)H(8)N(2))], the Pd(II) ion is four-coordinated in a slightly distorted square-planar environment by two N atoms of the chelating 1,10-phenanthroline (phen) ligand and two N atoms from two azide anions. The azido ligands are slightly bent with bond angles of 174.8?(4) and 174.5?(5)°. The complex mol-ecules are stacked in columns along the a axis and are connected by inter-molecular C-H?N hydrogen bonds, forming a three-dimensional network. In the columns, numerous inter-molecular ?-? inter-actions between the six-membered rings are present, the shortest ring centroid-centroid distance being 3.607?(2)?Å.

Project description:The title coordination polymer, [Pb(2)(N(3))(3)(NO(2))(C(12)H(8)N(2))(2)](n), has as the repeat unit a centrosymmetric dinuclear mol-ecule having azide and nitrite groups that bridge adjacent heterocycle-coordinated metal centers. One of the azide group uses its terminal ends to bridge whereas the nitrite group chelates to one metal atom and uses one of its O atoms to bridge. The azide and nitrite groups are disordered with respect to each other in a 1:1 ratio. Adjacent dinuclear mol-ecules are further bridged by the other two azide groups, generating a linear chain motif parallel to [010]. Half of the Pb atoms show a ?-dodeca-hedral coordination and the other half show a ?-penta-gonal-bipyramidal coordination.

Diaqua-bis-(perchlorato)(1,10-phenanthroline)copper(II).

Project description:In the title compound, [Cu(ClO(4))(2)(C(12)H(8)N(2))(H(2)O)(2)], the Cu(II) atom is coordinated in a square-planar fashion by the two N atoms of a chelating 1,10-phenanthroline ligand and by two water mol-ecules trans to the N atoms. The coordination sphere of the metal atom is augmented by O atoms of two weakly bonded perchlorate anions, thus yielding a strongly distorted CuN(2)O(4) octa-hedral environment. The crystal packing is stabilized by O-H⋯O hydrogen bonds between the water mol-ecules and the perchlorate anions. In addition, the organic mol-ecules are associated by π-π stacking inter-actions between symmetry-equivalent anti-parallel non-nitro-gen aromatic rings, with inter-planar distances of 3.543 (2) Å.

Tris(1,10-phenanthroline)cobalt(II) bis-(trichloro-acetate).

Project description:In the title complex, [Co(C(12)H(8)N(2))(3)](C(2)Cl(3)O(2))(2), the Co(II) ion lies on a twofold rotation axis and is coordinated by six N atoms from three bis-chelating 1,10-phenanthroline ligands in a distorted octa-hedral environment. The crystal structure is stabilized by weak inter-molecular C-H⋯O hydrogen bonds.

catena-Poly[[(1,10-phenanthroline)cobalt(II)]-di-?-azido].

Project description:In the crystal structure of the binuclear title complex, [Co(N(3))(2)(C(12)H(8)N(2))](n), each Co(II) cation is coordinated by two N atoms from one chelating 1,10-phenanthroline ligand and four azide ligands in a slightly distorted octa-hedral coordination. The two Co(II) cations of the binuclear complex are related by an inversion centre and are bridged by two symmetry-related azide ligands in both ?(1,1) and ?(1,3) modes. The ?(1,3) bridging mode gives rise to an infinite one-dimensional chain along the a axis, whereas the ?(1,1) bridging mode is responsible for the formation of the binuclear Co(II) complex.

Bis(acetonitrile-?N)(1,10-phenanthroline-?N,N')platinum(II) bis-(perchlorate).

Project description:The asymmetric unit of the title compound, [Pt(CH(3)CN)(2)(C(12)H(8)N(2))](ClO(4))(2), contains one half of a cationic Pt(II) complex and pair of half perchlorate anions, one of which is disordered over two sites in a 0.53?(3):0.47?(3) ratio. The complex and anions are disposed about a crystallographic mirror plane parallel to the ac plane passing through the Pt and Cl atoms. In the complex, the Pt(II) ion lies in a distorted square-planar environment defined by four N atoms of the chelating 1,10-phenanthroline ligand and two distinct acetonitrile mol-ecules. The component ions inter-act by means of inter-molecular C-H?O hydrogen bonds.

Bis(μ-4-nitro-phthalato)bis-[diaqua-(1,10-phenanthroline)manganese(II)].

Project description:In the title compound, [Mn(2)(C(8)H(3)NO(6))(2)(C(12)H(8)N(2))(2)(H(2)O)(4)], the Mn(II) atom in the centrosymmetric binuclear unit has a distorted octa-hedral geometry and is coordinated by a chelating 1,10-phenanthroline ligand, two monodentate carboxyl-ate anions from two 4-nitro-phthalates and two coordinated water mol-ecules. The two Mn(II) ions in the mol-ecule are bridged by two 4-nitro-phthalate anions, both in a bis-monodentate mode, which finally leads to the formation of the binuclear unit. Intra-molecular O-H⋯O hydrogen bonds between the coordinated and uncoordinated O atoms of one monodentate carboxyl-ate group and the corresponding coordinated water mol-ecules result in an eight-membered and two six-membered rings. In the crystal structure, inter-molecular O-H⋯O hydrogen bonds link the dinuclear mol-ecules into supra-molecular chains propagating parallel to [100].

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.
