[Malonato(2-)-?O,O']bis-(1,10-phenanthroline-?N,N')zinc(II) penta-hydrate.

ABSTRACT: In the title complex, [Zn(C(3)H(2)O(4))(C(12)H(8)N(2))(2)]·5H(2)O, the Zn(II) cation displays a distorted octa-hedral geometry, being coordinated by four N atoms from two 1,10-phenanthroline ligands and two O atoms from different carboxyl-ate groups of the chelating malonate dianion. In the crystal, the complexes are linked into a three-dimensional supra-molecular network by both O-H?O hydrogen-bonding inter-actions between water mol-ecules and the uncoordinated carboxyl-ate O atoms of neighboring mol-ecules, and aromatic ?-? stacking inter-actions between neighboring phenanthroline rings with centroid-centroid distances of 3.4654?(17) and 3.697?(2)?Å.

Project description:In the crystal structure of the title compound, [Zn(C(7)H(10)O(4))(C(12)H(8)N(2))(2)]·6H(2)O, the Zn(II) atom is coordinated by two carboxyl-ate O atoms of a mono-bidentate chelating pimelate anion (pimelic acid is hepta-nedioic acid) and four N atoms of two phenanthroline ligands, forming a considerably distorted octa-hedral ZnN(4)O(2) coordination geometry. The complexes are assembled into a three-dimensional network via C-H⋯O, C-H⋯π and π-π inter-actions. The mean inter-planar distance between adjacent phenanthroline ligands is 3.399 (2) Å.

Tris(1,10-phenanthroline-κN,N')zinc(II) bis-(4-bromo-benzoate) 6.5-hydrate.

Project description:In the title compound, [Zn(C(12)H(8)N(2))(3)](C(7)H(4)BrO(2))(2)·6.5H(2)O, the Zn(II) atom is coordinated by six N atoms from three 1,10-phenanthroline (phen) mol-ecules in a distorted octa-hedral geometry. The chelating phen ligands exhibit nearly perfect coplanarity (r.m.s. deviations of 0.048, 0.039 and 0.061 Å). The mean inter-planar distances of 3.51 (2) and 3.54 (4) Å between adjacent phen ligands indicate π-π stacking inter-actions, which connect the complex cations into chains along [101]. The 4-bromo-benzoate anions and the uncoordinated water mol-ecules, parts of which are not fully occupied, are linked by O-H⋯O hydrogen bonds. Two carboxyl-ate O atoms and one Br atom in the 4-bromo-benzoate anions are each disordered over two sites with occupancy factors of 0.60 and 0.40.

Aqua-(3-hydroxy-benzoato-κO)bis-(1,10-phenanthroline-κN,N')cobalt(II) 3-hydroxy-benzoate penta-hydrate.

Project description:The crystal structure of the title compound, [Co(C(7)H(5)O(3))(C(12)H(8)N(2))(2)(H(2)O)](C(7)H(5)O(3))·5H(2)O, consists of Co(II) complex cations, uncoordinated hydroxy-benzoate anions and uncoord-inated water mol-ecules. The Co(II) ion is coordinated by two phenanthroline ligands, a water mol-ecule and a 3-hydroxy-benzoate anion, and displays a distorted octa-hedral geometry. π-π stacking is observed between parallel phenanthroline ligands, the face-to-face separations being 3.454 (19) and 3.435 (7) Å. An extensive hydrogen-bonding network helps to stabilize the crystal structure. The hydroxybenzoate ligand is disordered over two positions, with site occupancy factors 0.6 and 0.4.

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.

Aqua-(4-bromo-benzoato-κO)bis-(1,10-phenanthroline-κN,N')zinc(II) 4-bromo-benzoate 1.5-hydrate.

Project description:In the title compound, [Zn(C(7)H(4)BrO(2))(C(12)H(8)N(2))(2)(H(2)O)](C(7)H(4)BrO(2))·1.5H(2)O, the Zn(II) atom is coordinated by four N atoms from two chelating 1,10-phenanthroline (phen) ligands, one O atom from a 4-bromo-benzoate ligand and one water mol-ecule, completing a distorted ZnN(4)O(2) octa-hedral geometry. The two phen ligands exhibit nearly perfect coplanarity (r.m.s. deviations = 0.027 and 0.031 Å), making a dihedral angle of 85.7 (1)°. The mean inter-planar distances of 3.36 (2) and 3.41 (3) Å between adjacent phen ligands indicate π-π stacking inter-actions. The uncoordinated water mol-ecules are partly occupied. One carboxyl-ate O atom and two Br atoms are each disordered over two sites, with occupancy factors of 0.60 and 0.40. In the crystal structure, O-H⋯O and C-H⋯O hydrogen bonds and π-π stacking inter-actions link the complex cations, uncoordinated 4-bromo-benzoate anions and water mol-ecules into a three-dimensional supra-molecular network. An intra-molecular O-H⋯·O hydrogen bond is observed in the cation.

Bis[2-(4-hy-droxy-phen-yl)acetato-κO]bis-(1,10-phenanthroline-κN,N')cadmium penta-hydrate.

Project description:In the title compound, [Cd(C(8)H(7)O(3))(2)(C(12)H(8)N(2))(2)]·5H(2)O, the Cd(II) ion is six-coordinated by two carboxylate O atoms of monodentate 2-(4-hy-droxy-phen-yl)acetate ligands and by four N atoms from two chelating 1,10-phenantroline ligands in a distorted trigonal-prismatic geometry. O-H⋯O hydrogen bonds between water mol-ecules and the complex mol-ecules result in the formation of a three-dimensional network. Four water mol-ecules act as single acceptors and double donors while the fifth water mol-ecule is involved as a single acceptor and single donor in an O-H⋯O inter-action and as a donor in an O-H⋯π inter-action.

Bis(2,9-dimethyl-1,10-phenanthroline)copper(I) penta-cyanido-nitro-soferrate(II).

Project description:The asymmetric unit of the title complex [Cu(C14H12N2)2]2[Fe(CN)5(NO)], consists of a [Cu(dmp)2](+) cation (dmp is 2,9-dimethyl-1,10-phenanthroline) and half an [Fe(CN)5(NO)](2-) anion. The anion is disordered across an inversion center with the Fe(II) ion slightly offset (ca 0.205Å) from the inversion center in the direction of the disordered trans-coordinating CN/NO ligands. The anion has a distorted octa-hedral coordination geometry. The Cu(I) ion is coordinated by two phenanthroline ligands in a distorted tetra-hedral geometry. The dihedral angle between the phenanthroline ligands is 77.16?(4)?Å. In the crystal, the cations are connected to the anions by weak C-H?N hydrogen bonds. In addition, weak ?-? stacking inter-actions are observed, with centroid-centroid distances in the range 3.512?(3)-3.859?(3)?Å.

(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.

Bis[tris-(1,10-phenanthroline)nickel(II)] tris-[dicyanidoargentate(I)] nitrate 4.2-hydrate.

Project description:The title compound, [Ni(C(12)H(8)N(2))(3)](2)[Ag(CN)(2)](3)(NO(3))·4.2H(2)O, crystallizes with two independent [Ni(phen)(3)](2+) cations (phen is 1,10-phenanthroline; both Ni atoms have threefold symmetry and N(6) donor sets), three near-linear [Ag(CN)(2)](-) anions, one nitrate anion (N site symmetry 3) and 4.2 water mol-ecules of crystallization, some of which are disordered. The [Ag(CN)(2)](-) anions are situated within cavities created by the phenanthroline ligands of adjacent [Ni(phen)(3)](2+) cations. Some short C-H⋯O and C-H⋯N inter-actions may help to establish the packing.

Aqua-bis-(benzoato-?O)(1,10-phenanthroline-?N,N')zinc(II).

Project description:The Zn atom in the title compound, [Zn(C(7)H(5)O(2))(2)(C(12)H(8)N(2))(H(2)O)], is five-coordinate in a distorted trigonal-bipyramidal coordination environment involving two O atoms of two monodentate benzoates, two N atoms of a 1,10-phenanthroline mol-ecule and one O atom of a water mol-ecule. The axial positions are occupied by a carboxyl-ate O atom from the benzoate ligand and an N atom from the 1,10-phenanthroline ligand [N-Zn-O = 146.90?(7)°]. The water mol-ecule forms an intra-molecular O-H?O hydrogen bond; an inter-molecular O-H?O hydrogen bond gives rise to a dimer.
