Catena-Poly[[(1,10-phenanthroline-?N,N')lead(II)]-di-?-nitrato-?O,O':O'';?O:O',O''-[(1,10-phenanthroline-?N,N')lead(II)]-bis-(?-2,2,2-trichloro-acetato-?O:O')].

ABSTRACT: In the title Pb(II) complex, [Pb(2)(C(2)Cl(3)O(2))(2)(NO(3))(2)(C(12)H(8)N(2))(2)](n), the 1,10-phenanthroline ligand is chelating, the nitrate anion chelates one Pb(II) ion and simultaneously bridges a neighbouring Pb(II) ion via the third O atom, and the trichloro-acetate anion is bidentate, bridging two Pb(II) ions. The coordination geometry is based on a penta-gonal-bipramidal geometry defined by an N(2)O(5) donor set with no obvious stereochemical role for the lead-bound lone pair of electrons. The coordination polymer has a zigzag topology along [010] and comprises alternating eight-membered {PbONO}(2) and {PbOCO}(2) rings.

Di-?-chlorido-bis-[(1,10-phenanthroline-?N,N')(trichloro-acetato-?O)copper(II)].

Project description:The title compound, [Cu(2)(C(2)Cl(3)O(2))(2)Cl(2)(C(12)H(8)N(2))(2)], features a centrosymmetric binuclear complex. The coordination geometry around the Cu(II) atom is square-pyramidal, comprising two N atoms from a symmetrically chelating 1,10-phenanthroline ligand, one O atom from a trichloro-acetate ligand and two Cl(-) anions. In addition, there is a weak intra-molecular Cu?O inter-action of 2.9403?(14)?Å involving the carbonyl O atom of the trichloro-acetate ligand. The central Cu(2)Cl(2) core takes the form of a rhombus, owing to the disparate Cu-Cl bond lengths. Mol-ecules are connected in the crystal structure by C-H?Cl and C-H?O inter-actions.

Chloridobis(1,10-phenanthroline-?N,N')(2,2,2-trichloro-acetato-?O)cobalt(II).

Project description:The title compound, [Co(C(2)Cl(3)O(2))Cl(C(12)H(8)N(2))(2)], was obtained by the reaction of trichloro-acetic acid and CoCl(2) in the presence of 1,10-phenanthroline. The Co(II) ion exhibits a distorted octa-hedral geometry, with three N atoms from two 1,10-phenanthroline ligands and the Cl(-) ion in the equatorial plane and one O atom from the trichloro-acetate ligand and one phenanthroline N atom in axial positions. This compound is isostructural with the analogous Mn(II) complex. The trichloro-methyl group of the trichloro-acetate ligand is disordered over two positions with occupancies of 0.190?(5) and 0.810?(5).

catena-Poly[[(2,9-dimethyl-1,10-phenanthroline-?(2)N,N')lead(II)]-di-?-bromido].

Project description:In the title compound, [PbBr(2)(C(14)H(12)N(2))](n), the Pb(II) atom lies on a twofold rotation axis. The N-heterocycle-chelated Pb(II) atom exists in a distorted octa-hedral geometry owing to two long Pb?Br inter-actions [2.9562?(5) and 3.2594?(5)?Å]. These result in a zigzag chain running along the c axis. The lone pair is stereochemically inactive.

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.

Project description:In the crystal structure of the title compound, [Mn(NO(3))(2)(C(12)H(8)N(2))](n), the Mn(II) atoms are linked by nitrate ligands to form a chain. Each Mn(II) atom is five-coordinated by two N atoms of a 1,10-phenanthroline ligand and three O atoms of two nitrates within a trigonal-bipyramidal coordination geometry. In the crystal structure, the chains are linked by hydrogen bonds into a polymeric ribbon structure.

Project description:The title complex, [Pr(2)(C(8)H(7)O(3))(6)(C(12)H(8)N(2))(2)](n), which has an inversion centre midway between the two Pr(III) atoms of the structural unit, forms a one-dimensional polymer bridged alternately by either two bidentate, or two bidentate and two terdentate, phenoxy-acetate carboxyl-ate groups. Each Pr(III) atom is thus nine-coordinated by two N atoms of a 1,10-phenanthroline ligand and seven O atoms from six phenoxy-acetate ligands. The coordination geometry at the Pr(III) atom is distorted tricapped trigonal prismatic. One phenyl ring is disordered over two positions; the site occupancy factors are ca 0.6 and 0.4.

Di-?-benzoato-?O,O':O;?O:O,O'-bis-[(acetato-?O)(1,10-phenanthroline-?N,N')lead(II)] dihydrate.

Project description:The title compound, [Pb(2)(CH(3)COO)(2)(C(7)H(5)O(2))(2)(C(12)H(8)N(2))(2)]·2H(2)O, consists of dimeric units built up around a crystallographic centre of symmetry and two non-coordinating water mol-ecules. Each Pb(II) unit is six-coordinated by a bidentate 1,10-phenanthroline (phen) ligand, a monodentate acetate anion and a bidentate benzoate anion, which also acts as a bridge linking the two Pb(II) atoms. The crystal packing is stabilized by O-H?O hydrogen bonds and by ?-? inter-actions between the phen rings of neighboring mol-ecules, with a centroid-centroid distance of 3.577?(3)?Å.

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.

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.
