Bis(4,7-dichloro-1,10-phenanthroline-?N,N')bis-(dicyanamido-?N)copper(II).

ABSTRACT: In the title compound, [Cu(C(2)N(3))(2)(C(12)H(6)Cl(2)N(2))(2)], the Cu(II) atom is coordinated by two chelating 4,7-dichloro-1,10-phenanthroline (4,7-Cl-phen) ligands and two dicyanamide (dca) ligands in a cis arrangement, forming a distorted octa-hedral geometry. The equatorial plane is occupied by three N atoms from two 4,7-Cl-phen ligands and one N atom from a dca ligand at shorter Cu-N distances. Due to the Jahn-Teller effect, the axial positions are occupied by a 4,7-Cl-phen N atom and a dca N atom at longer Cu-N distances. The dca ligands are nearly planar, with a maximum deviations of 0.006?(1)?Å. The crystal structure is stabilized by weak C-H?N hydrogen bonds, with cyanide N atoms as acceptors, and ?-? inter-actions between adjacent phenyl rings [centroid-centroid distance = 3.725?(3)?Å].

Project description:In the title complex, [Cu(C(2)HCl(2)O(2))(2)(C(12)H(8)N(2))(H(2)O)], the Cu(II) ion has a distorted square-pyramidal coordination geometry. The equatorial positions are occupied by two N atoms from a 1,10-phenanthroline ligand [Cu-N = 1.994 (3) and 2.027 (3) Å] and two O atoms from dichloro-acetate ligands and a water mol-ecule [Cu-O = 1.971 (2) and 1.939 (2) Å].

Project description:In the title compound, [Cu(C(5)H(7)O(2))(C(2)N(3))(C(12)H(8)N(2))]·2H(2)O, the Cu(II) atom is five-coordinated in a square-pyramidal geometry with two acetyl-acetonate O and two phenanthroline N atoms forming the base.

(Formato-κO)bis-(1,10-phenanthroline-κN,N')copper(II) formate hexa-hydrate.

Project description:In the title compound, [Cu(CHO(2))(C(12)H(8)N(2))(2)]CHO(2)·6H(2)O, the Cu atom is coordinated in a distorted trigonal-bipyramidal fashion by an O atom of the formate ligand and four N atoms of two phenanthroline ligands with Cu-O and Cu-N distances of 2.020 (3) and 1.978 (3)-2.177 (3) Å, respectively. Hydrogen bonding O-H⋯O between water molecules and between water anions as well as π-π inter-actions [centroid-centroid distances between phen rings = 3.38 (7) and 3.40 (5) Å] are responsible for the supra-molecular assembly.

Tetra-aqua-(1,10-phenanthroline-κN,N')magnesium(II) bis-[(2,4-dichloro-phen-yl)acetate].

Project description:In the mononuclear title complex, [Mg(C(12)H(8)N(2))(H(2)O)(4)](C(8)H(5)Cl(2)O(2))(2), each Mg(II) ion is hexa-coordinated by two N atoms from a 1,10-phenanthroline ligand [Mg-N = 2.233 (2) Å] and four water mol-ecules [Mg-OW = 2.033 (2) and 2.043 (1) Å] in a distorted octa-hedral geometry. A twofold rotation axis passes through the Mg atom.

Bis(1,10-phenanthroline-κN,N')(sulfato-O)copper(II) ethane-1,2-diol monosolvate.

Project description:In the title compound, [Cu(SO(4))(C(12)H(8)N(2))(2)]·C(2)H(6)O(2), the Cu(II) ion is five-coordinated in a distorted square-pyramidal manner by four N atoms from two chelating 1,10-phenanthroline (phen) ligands and one O atom from a monodentate sulfate anion. The four N atoms comprise a square and the one O atom the apex of a square pyramid. The two chelating N(2)C(2) groups are oriented at 71.1 (2)°. In the crystal, the components are connected by inter-molecular O-H⋯O hydrogen bonding. 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.

Project description:The Cu(II) atoms in the two independent mol-ecules of the title compound, [Cu(C(7)H(5)O(3))(2)(C(14)H(12)N(2))], are each coordinated by a bidentate 2,9-dimethyl-1,10-phenanthroline (dmphen) mol-ecule and two monodentate 2-hydroxy-benzoate anions in a distorted tetra-hedral geometry. The crystal packing is stabilized by intra-molecular hydrogen bonding and π-π inter-actions between the dmphen rings of neighboring mol-ecules, with distances between their ring planes of 3.5670 (4) and 3.5181 (9) Å.

Di-μ-glutarato-κO:O-bis-[aqua-(1,10-phenanthroline-κN,N')copper(II)].

Project description:In the centrosymmetric dinuclear title complex, [Cu(2)(C(5)H(6)O(4))(2)(C(12)H(18)N(2))(2)(H(2)O)(2)], the Cu(II) atom displays a dis-torted square-pyramidal coordination environment with the basal plane occupied by two phenanthroline N atoms and two O atoms from different glutarate dianions while a water mol-ecule is located at the apical position. Of the two water H atoms, one is engaged in an intra-molecular hydrogen bond with a free oxygen of the dianion whereas the second is engaged in an inter-molecular hydrogen bond, building a corrugated layer parallel to (100). These layers are further connected through π-π stacking inter-actions involving symmetry-related phenanthroline rings [centroid-centroid distance = 3.5599 (17) and 3.5617 (18) Å], building a three dimensionnal network. C-H⋯π inter-actions involving the phenanthroline ring system are also observed.
