(Nitrato-?(2) O,O')bis-(1,10-phenanthroline-?(2) N,N')copper(II) tricyano-methanide.

ABSTRACT: The title compound, [Cu(NO3)(C12H8N2)2][C(CN)3], is formed of discrete [Cu(NO3)(phen)2](+) complex cations (phen is 1,10-phenanthroline) and C(CN)3(-) counter-anions. The Cu(II) atom has an asymmetric tetragonal-bipyramidal (4 + 1+1) stereochemistry with a pseudo-C2 symmetry axis bis-ecting the nitrate ligand and passing through the Cu(II) atom between the two phen ligands. The four N atoms of the phen ligands coordinate to the Cu(II) atom with Cu-N distances in the range 1.974?(2)-2.126?(2)?Å, while the two O atoms coordinate at substanti-ally different distances [2.154?(2) and 2.586?(2)?Å]. The structure is stabilized by C-H?O hydrogen bonds and weak ?-? inter-actions between nearly parallel benzene and pyridine rings of two adjacent phen mol-ecules, with centroid-centroid distances of 3.684?(2) and 3.6111?(2)?Å, and between ?-electrons of the tricyano-methanide anion and the pyridine or benzene rings [N?(ring centroid) distances = 3.553?(3)-3.875?(3)?Å].

Tris(5,6-dimethyl-1,10-phenanthroline-κ(2) N,N')iron(II) bis-(tricyano-methanide).

Project description:The title compound, [Fe(C14H12N2)3](C4N3)2, consists of one [Fe(dimephen)3](2+) complex cation (dimephen = 5,6-dimethyl-1,10-phenanthroline) and two uncoordinating tcm anions (tcm = tricyano-methanide). In the complex cation, the Fe(II) atom is coordinated by six N atoms from three chelating dimephen ligands at an average Fe-N distance of 1.963 (4) Å giving a distorted octa-hedral geometry. The crystal structure is stabilized by weak C-H⋯N hydrogen bonds and C N⋯π inter-actions between planar [maximum deviations of 0.024 (3) and 0.015 (3) Å] tcm anions and pyridine rings of dimephen [N2⋯centroid = 3.531 (3) and 3.726 (3) Å; C N⋯centroid = 96.4 (2) and 97.1 (2)°].

trans-Bis(nitrato-κO)bis-(1,10-phenanthroline-κ(2)N,N')manganese(II).

Project description:In the title compound, [Mn(NO(3))(2)(C(12)H(8)N(2))(2)], the Mn(II) atom lies on a twofold rotation axis, and is six-coordinated in a distorted trans-N(4)O(2) octa-hedral environment by four N atoms from two 1,10-phenanthroline ligands and two O atoms from two nitrate anions. The nitrate anion is disordered about a twofold rotation axis with fixed occupancy factors of 0.5. In the crystal, mol-ecules are linked by weak C-H⋯O hydrogen bonds and π-π stacking inter-actions [centroid-centroid distance = 4.088 (5) Å] into a three-dimensional supra-molecular network.

Bis(cinnamato-κO)(1,10-phenanthroline-κ(2) N,N')copper(II).

Project description:The title mononuclear Cu(II) complex, [Cu(C9H7O2)2(C12H8N2)], is comprised of a Cu(II) cation, two cinnamate (L (-)) ligands and a 1,10-phenanthroline (phen) ligand. The Cu(II) atom and phen ligand lie on a twofold rotation axis. The Cu(II) atom is coordinated by two O atoms from two carboxyl-ate groups of two (L (-)) ligands and two N atoms from one phen ligand, exhibiting a distorted square-planar geometry. In the crystal, mol-ecules are assembled into supra-molecular chains parallel to the c axis through weak C-H⋯O hydrogen bonds involving the phen and cinnamate ligands.

Bis(2,2':6',2''-terpyridine)cobalt(II) bis-(tricyano-methanide).

Project description:The title complex, [Co(C(15)H(11)N(3))(2)](C(4)N(3))(2), is built up from discrete [Co(terpy)(2)](2+) cations (terpy is 2,2':6',2''-terpyridine) and [C(CN)(3)](-) anions. In the cation, the Co(II) atom is coordinated by two terpy mol-ecules, giving a distorted octa-hedral geometry. The tricyano-methanide anions are not directly coordinated to the Co(II) atom, but some weak C-H⋯N hydrogen bonds involving the terminal N atoms of the tricyaomethanide ions and the terpyridine H atoms link anions and cations building a three-dimensional network.

Poly[diaqua-bis-(nitrato-κ²O,O')bis-(1,10-phenanthroline-κ²N,N')-μ₃-succinato-dicadmium].

Project description:In the title coordination polymer, [Cd₂(C₄H₄O₄)(NO₃)₂(C₁₂H₈N₂)₂(H₂O)₂](n), the Cd(II) ion is seven-coordinated within a distorted penta-gonal-bipyramidal O₅N₂ environment. The succinate anions, located on an inversion centre, adopt a bis-monodentate bridging mode, leading to the formation of rods along [100]. The rods are connected by O-H⋯O hydrogen bonds between the coordinating water mol-ecules and nitrate O atoms of adjacent rods; the same type of hydrogen bonds are also observed between water and carboxyl-ate O atoms within the rods. π-π stacking inter-actions with a minimum plane-to-plane separation of 3.462 (2) Å occur between phenanthroline ligands.

Bis(1,10-phenanthroline-κ(2) N,N')(sulfato-κO)copper(II) ethanol monosolvate.

Project description:The crystal structure of the title compound, [Cu(SO4)(C12H8N2)2]·C2H5OH, arises from the assembly of the neutral complex [Cu(SO4)(C12H8N2)2] and an ethanol solvent mol-ecule. The Cu(II) ion is five-coordinate, surrounded by two pairs of N atoms from two independent N,N'-chelating 1,10-phenanthroline ligands, and one O atom of monodentate sulfate ligand, in a distorted trigonal-bipyramidal fashion. Spatial orientation of the ligands and the assembly in the solid state are stabilized by the C-H⋯O hydrogen-bonding inter-actions, established between the O atoms (from the sulfate ligand and the ethanol mol-ecule) and the neighbouring 1,10-phenanthroline mol-ecules. There is also an offset face-to-face π-π stacking between the 1,10-phenanthroline ligands. The ethanol solvent mol-ecule is disordered over two orientations in the ratio 0.663 (10):0.337 (10). The crystal examined was subject to racemic twinning and the refined twin fraction was 0.346 (19).

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.

Nitrato(1,10-phenanthroline)(1H-1,2,4-triazole-3-carboxyl-ato)copper(II).

Project description:In the title complex, [Cu(C(3)H(2)N(3)O(2))(NO(3))(C(12)H(8)N(2))], the Cu(II) ion is coordinated by an N and an O atom from a bidentate 1H-1,2,4-triazole-3-carboxyl-ate (TRIA) ligand, two N atoms from a 1,10-phenanthroline (phen) ligand, and an O atom from a nitrate ligand in a slightly distorted square-pyramidal environment. In the crystal structure, inter-molecular N-H?O hydrogen bonds link mol-ecules into one-dimensional chains propagating along the b axis direction.

Bis(2,9-dimethyl-1,10-phenanthroline-κN,N')bis-(nitrato-κO,O')lead(II).

Project description:In the title complex, [Pb(NO(3))(2)(C(14)H(12)N(2))(2)], the lead ion is chelated by two 2,9-dimethyl-1,10-phenanthroline (dmphen) ligands and two nitrate anions in a slightly distorted square-anti-prismatic geometry. Intra- and inter-molecular π-π stacking is present in the crystal structure, and the centroid-centroid distances between the benzene and pyridine rings of adjacent dmphen ligands are 3.492 (3) and 3.592 (3) Å, respectively. Inter-molecular C-H⋯O hydrogen bonds and C-H⋯π inter-actions help to stabilize the crystal structure.

Bis(1,10-phenanthroline-κ(2) N,N')(sulfato-O)copper(II) butane-2,3-diol monosolvate.

Project description:The title compound, [Cu(SO4)(C12H8N2)2]·C4H10O2, is comprised of neutral monomeric complex and butane-2,3-diol solvent mol-ecules. In the complex, the Cu(II) ion is in a distorted square-pyramidal coordination environment defined by four N atoms from two chelating 1,10-phenanthroline ligands and one O atom from a monodentate sulfate anion; the O atom is at the apex. The two chelating N2C2 groups subtend a dihedral angle of 85.8 (4)°. In the crystal, the neutral monomeric complex and butane-2,3-diol solvent mol-ecules are held together by O-H⋯O hydrogen bonding, which leads to additional stabilization of the structure. The presence of pseudosymmetry in the structure suggests the higher symmetry space group C2/c, but attempts to refine the structure in this space group resulted in an unsatisfactory model and high R and wR values. The sulfate anion is disordered over two sets of sites with occupancies of 0.55 (1) and 0.45 (1).
