Diaqua-bis(1,10-phenanthroline)magnesium dichromate(VI) 1,10-phenanthroline disolvate.

ABSTRACT: In the title compound, [Mg(C(12)H(8)N(2))(2)(H(2)O)(2)][Cr(2)O(7)]·2C(12)H(8)N(2), the cation and anion are situated on a twofold rotation axis. The Mg(II) ion is coordinated by four N atoms from two 1,10-phenanthroline ligands and two O atoms from coordinated water mol-ecules in a distorted octa-hedral geometry. Inter-molecular O-H?N and O-H?O hydrogen bonds and ?-? inter-actions between the aromatic rings [shortest centroid-centroid separation = 3.527?(2)?Å] link the cations, anions and 1,10-phenanthroline solvent mol-ecules into a hydrogen-bonded cluster.

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.

Bis(?-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].

Diaqua-bis-(1,10-phenanthroline-?N,N')cadmium sulfate hexa-hydrate.

Project description:The title compound, [Cd(C(12)H(8)N(2))(2)(H(2)O)(2)]SO(4)·6H(2)O, was obtained unexpectedly during an attempt to synthesize a cadmium complex with bidentate bridging sulfate ligands via hydro-thermal synthesis. The Cd(II) metal ion is six-coordinated by two chelating 1,10-phenanthroline ligands and two water mol-ecules, resulting in a distorted octa-hedral geometry for the metal ion. The two chelating N(2)C(2) groups are almost perpendicular to each other [dihedral angle = 86.75?(2)°]. In the crystal, the [Cd(C(12)H(8)N(2))(2)(H(2)O)(2)](2+) complex cations join with the sulfate anions through two O(water)-H?O(sulfate) hydrogen bonds. These ion pairs are further inter-linked into a two-dimensional supermolecular structure via additional O-H?O hydrogen bonds.

Poly[diaqua-bis-(nitrato-?²O,O')bis-(1,10-phenanthroline-?²N,N')-??-succinato-dicadmium].

Project description:In the title coordination polymer, [Cd?(C?H?O?)(NO?)?(C??H?N?)?(H?O)?](n), the Cd(II) ion is seven-coordinated within a distorted penta-gonal-bipyramidal O?N? 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. ?-? stacking inter-actions with a minimum plane-to-plane separation of 3.462?(2)?Å occur between phenanthroline ligands.

cis-Bis(1,10-phenanthroline-?N,N')bis-(thio-cyanato-?N)magnesium(II).

Project description:The title compound, [Mg(NCS)(2)(C(12)H(8)N(2))(2)], has been synthesized from the hydro-thermal reaction of MgCl(2), KSCN, 1,10-phenanthroline and H(2)O. Its structure is isotypic with the Mn(II), Fe(II), Co(II), Ni(II), Cu(II) and Zn(II) analogues. The Mg(II) cation has a slightly distorted octa-hedral geometry containing four N atoms from two 1,10-phenanthroline mol-ecules and two N atoms from two thio-cyanate anions. The asymmetric unit contains one-half mol-ecule, and the complete complex has 2 symmetry.

Diaqua-bis-(1,10-phenanthroline-?N,N')manganese(II) sulfate hexa-hydrate.

Project description:In the title compound, [Mn(C(12)H(8)N(2))(2)(H(2)O)(2)]SO(4)·6H(2)O, the complex cations assemble into positively charged sheets parallel to (010) via inter-molecular ?-? stacking inter-actions with a mean interplanar distance of 3.410?(6) along [100] and 3.465?(5)?Å along [001]. The sulfate anions and uncoordinated water mol-ecules are inter-connected between these layers by hydrogen bonds, forming negatively charged layers which are linked to the positive layers through O-H?O hydrogen bonds, forming a three-dimensional architecture. Both the positive and negative sheets are stacked along [010] in an ?ABAB? sequence, the A layers being shifted by 1/2a along [100] with respect to the B layers. One of the uncoordinated water molecules is equally disordered over two positions.

Project description:In the title compound, C(26)H(14)N(4)S(2)·2CH(2)Cl(2), the two pendant benzothia-zole groups are slightly twisted with respect to the phenanthroline core [dihedral angles = 1.03?(7) and 9.05?(5)°]. Weak inter-molecular C-H?N and C-H?Cl inter-actions occur in the crystal structure.

Project description:In the title complex, [Ni(NCS)(2)(C(14)H(13)N(3))(2)]·2CH(3)OH, the Ni(II) atom lies on a crystallographic twofold rotation axis and is in a slightly distorted octa-hedral NiN(6) coordination environment. The crystal structure is stabilized by a combination of weak ?-? stacking inter-actions between symmetry-related 1,10-phenanthroline ligands [centroi-centroid distance between benzene rings = 3.5936?(18)?Å] and weak O-H?S, C-H?O and C-H?S hydrogen bonds between methanol and complex mol-ecules.

Diaqua-(2,6-dihy-droxy-benzoato-?O,O)bis-(2,6-dihy-droxy-benzoato-?O)bis-(1,10-phenanthroline-?N,N')lanthanum(III)-1,10-phenanthroline (1/1).

Project description:In the title compound, [La(C(7)H(5)O(4))(3)(C(12)H(8)N(2))(3)(H(2)O)(2)]·C(12)H(8)N(2), the La(III) atom is coordinated by four N atoms from two chelating 1,10-phenanthroline (phen) ligands, four O atoms from three 2,6-dihy-droxy-benzoate (DHB) anions (one monodentate, the other bidentate) and two water O atoms, completing a distorted LaN(4)O(6) bicapped square-anti-prismatic geometry. Within the mononuclear complex mol-ecule, intra-molecular ?-? stacking inter-actions are observed, the first between a coordinated phen mol-ecule and a DHB ligand [centroid-centroid distance = 3.7291?(16)?Å], and the second between a coordinated phen mol-ecule and an uncoordinated phen ligand [centroid-centroid distance = 3.933?(2)?Å]. Inter-molecular ?-? stacking is observed between adjacent complexes [inter-planar distance = 3.461?(3)?Å]. Intra- and inter-molecular O-H?O hydrogen bonds are observed in the DHB ligands and between a water mol-ecule and DHB ligands, respectively. O-H?N hydrogen bonds are also observed in the DHB ligands and between uncoordinated phen mol-ecules and aqua ligands.

(Benzoato-?O)bis-(1,10-phenanthroline-?N,N')copper(II) chloride benzoic acid disolvate.

Project description:In the title complex, [Cu(C(7)H(5)O(2))(C(12)H(8)N(2))(2)]Cl·2C(6)H(5)CO-OH, the Cu(II) ion is coordinated by one carboxyl-ate O atom from a benzoate anion and four N atoms from two phenantroline ligands in a distorted five-coordinate trigonal-bipyramidal CuON(4) chromophore. The Cu(2+) and the Cl(-) ion are imposed by a twofold rotation axiss which also bisects the equally disordered benzoate anion. In the crystal, the mol-ecules are assembled into chains along [010] by C-H?Cl, O-H?Cl and C-H?O hydrogen-bonding inter-actions. The resulting chains are further connected into two-dimensional supra-molecular layers parallel to [100] by inter-chain ??? stacking inter-actions [centroid-centroid distance = 3.823?(5)?Å] between the phenanthroline ligands and the benzoic acid mol-ecules, and by C-H?O hydrogen-bonding inter-actions. Strong ??? stacking inter-actions between adjacent phenantroline ligands [3.548?(4)?Å] assemble the layers into a three-dimensional supra-molecular architecture.
