Bis(2-fluoro-benzoato-?O,O')bis-(1,10-phenanthroline-?N,N')lead(II) dihydrate.

ABSTRACT: In the title compound, [Pb(C(7)H(4)FO(2))(2)(C(12)H(8)N(2))(2)]·2H(2)O, the Pb(II) atom is coordinated by four N atoms from two bidentate chelating 1,10-phenanthroline (phen) ligands and four O atoms from two 2-fluoro-benzoate ligands in an irregular polyhedral coordination geometry. Two carboxyl-ate O atoms and one F atom are each disordered over two sites with occupancy factors of 0.60 and 0.40. The dihedral angle between the two phen ligands is 89.9?(1)°. The mean inter-planar distances are alternatively of 3.44?(3) and 3.45?(3)?Å, indicating ?-? stacking inter-actions between the neighboring phen ligands. In the crystal, O-H?O, O-H?F and C-H?O hydrogen bonds link the complex mol-ecules and uncoordinated water mol-ecules into a supra-molecular network.

Project description:In the title compound, [Pb(C(7)H(4)FO(2))(2)(C(12)H(8)N(2))(2)(H(2)O)(0.5)]·2H(2)O, the Pb(II) atom is coordinated by four N atoms from two bidentate chelating 1,10-phenanthroline (phen) ligands, four O atoms from two 2-fluoro-benzoate ligands and a half-occupied water mol-ecule in an irregular coordination geometry.

Aqua-bis-(3-fluoro-benzoato-?O)(1,10-phenanthroline-?N,N')copper(II).

Project description:In the title compound, [Cu(C(7)H(4)FO(2))(2)(C(12)H(8)N(2))(H(2)O)], the coordination around the Cu(II) atom is square-pyramidal. The equatorial positions are occupied by two N atoms from a 1,10-phenanthroline ligand [Cu-N = 2.008?(3) and 2.019?(3)?Å] and two O atoms from 3-fluoro-benzoate ligands and a water mol-ecule [Cu-O = 1.950?(2) and 1.978?(2)?Å]. One O atom from another 3-fluoro-benzoate ligand occupies the apical positon [Cu-O = 2.210?(2)?Å]. Hydrogen bonds occur between coordinated water mol-ecules and benzoate ligands, while O-H?O, C-H?O, C-H?F and ?-? stacking [centroid-centroid distance = 3.731?(2)?Å] inter-actions consolidate the crystal packing.

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)-2-chloro-benzoato-?O:O')bis-[(2-chloro-benzoato-?O)(1,10-phenanthroline-?N:N')copper(II)] dihydrate.

Project description:In the title compound, [Cu(2)(C(7)H(4)ClO(2))(4)(C(12)H(8)N(2))(2)]·2H(2)O, the two crystallographically independent dinuclear complex mol-ecules, A and B, have different Cu?Cu separations, viz. 3.286?(1)?Å in A and 3.451?(1)?Å in B. Both independent mol-ecules reside on inversion centres, so the asymmetric unit contains a half-mol-ecule each of A and B and two water mol-ecules. Each Cu atom has a square-pyramidal environment, being coordinated by two O atoms from two bridging 2-chloro-benzoate ligands, one O atom from a monodentate 2-chloro-benzoate ligand and two N atoms from a 1,10-phenanthroline ligand. The water mol-ecules can also be considered as coordinating ligands, which complete the coordination geometry up to distorted octa-hedral with elongated Cu-O distances, viz. 3.024?(3)?Å in A and 2.917?(3)?Å in B. In the crystal, weak inter-molecular C-H?O inter-actions contribute to the consolidation of the crystal packing.

catena-Poly[[(1,10-phenanthroline)lead(II)]bis-(?-5-chloro-2-hy-droxy-benzoato)].

Project description:In the title polymer, [Pb(C(7)H(4)ClO(3))(2)(C(12)H(8)N(2))](n), the Pb(II) ion displays a distorted pseudo-octa-hedral coordination geometry. The metal center is coordinated by six O atoms from four 5-chloro-salicylate ligands and two N atoms from a chelating phenanthroline ligand. The polymeric structure is built up from bridging carboxyl-ate O atoms, forming chains along [100]. The crystal structure is stabilized by ?-? inter-actions between the 1,10-phenanthroline and 5-chloro-salicylate ligands, the shortest centroid-centroid separation between neighbouring aromatic rings being 3.652?(1)?Å.

Bis(benzoato-?O,O')(1,10-phenanthroline-?N,N')lead(II) benzoic acid mono-solvate.

Project description:The reaction of lead acetate, benzoic acid and 1,10-phenanthroline (phen) in aqueous solution yielded the title complex, [Pb(C(7)H(5)O(2))(2)(C(12)H(8)N(2))]·C(7)H(6)O(2). In the crystal, the Pb(II) ion is hexa-coordinated by two N atoms from one 1,10-phenanthroline ligand and four O atoms from two chelate benzoate anions. If the second benzoate ligand is treated as one coordination site, the overall coordination may be represented as a distorted pseudo-square pyramid. An inter-molecular O-H?O hydrogen bond links the solvent benzoic acid mol-ecule with a metal-coordinated benzoate ligand. The shortest Pb?Pb distance is 3.864?(4)?Å, indicating a weak metal-metal inter-action. Two complex mol-ecules related by an inversion centre form dimeric units via Pb?O inter-actions of 3.206?(4)?Å.

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

Project description:In the centrosymmetric dinuclear title compound, [Pb(2)(C(7)H(5)O(2))(4)(C(12)H(8)N(2))(2)], two Pb(2+) ions are connected by two tridentate bridging benzoate anions. The Pb(2+) ion is seven-coordinated by five O atoms from three benzoate anions and two N atoms from the 1,10-phenanthroline ligands. The benzoate anions adopt two different coordination modes, one bidentate-chelating and one tridentate bridging-chelating. The three-dimensional supra-molecular framework is achieved by inter-molecular ?-? stacking inter-actions, with a shortest centroid-centroid distance of 3.617?(4)?Å.

Aqua-(3-fluoro-benzoato-?O)(3-fluoro-benzoato-?O,O')(1,10-phenanthroline-?N,N')cobalt(II).

Project description:In the title compound, [Co(C(7)H(4)FO(2))(2)(C(12)H(8)N(2))(H(2)O)], the Co(II) ion is coordinated by two O atoms from one 3-fluoro-benzoate (fb) ligand and one O atom from another fb ligand, two N atoms from the 1,10-phenanthroline ligand and a water mol-ecule in a distorted octa-hedral geometry. An intra-molecular O-H?O hydrogen bond occurs. Inter-molecular O-H?O hydrogen bonds link pairs of mol-ecules into centrosymmetric dimers. Weak inter-molecular C-H?O and C-H?F hydrogen bonds and ?-? inter-actions between the aromatic rings [shortest centroid-centroid distance = 3.4962?(2)?Å] further stabilize the crystal 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.

Crystal structure of bis-(?-2,3,4,5-tetra-fluoro-benzoato-?(2) O:O')bis-[(1,10-phen-anthroline-?(2) N:N')(2,3,4,5-tetra-fluoro-benzoato-?O)copper(II)] dihydrate.

Project description:In the title compound, [Cu2(C7HF4O2)4(C12H8N2)2]·2H2O, the Cu(II) ion has a square-pyramidal coordination sphere. The basal plane consists of two N atoms [Cu-N = 2.008?(3) and 2.032?(3)?Å] from the phenanthroline ligand, and of two carboxyl-ate O atoms [Cu-O = 1.942?(3) and 1.948?(3)?Å] from two 2,3,4,5-tetra-fluoro-benzoate anions. Another 2,3,4,5-tetra-fluoro-benzoate anion provides the apical carboxyl-ate O atom [Cu-O = 2.262?(3)?Å] and bridges two Cu(II) ions into a binuclear centrosymmetric dimer. Intra-molecular ?-? inter-actions between one of the tetra-fluoro-benzene rings and the middle of the phenenanthroline rings [3.617?(3)?Å] stabilize the mol-ecular configuration. O-H?O hydrogen bonds between the lattice water mol-ecules and the unbound carboxyl-ate O atoms of the metal complexes leads to the formation of a chain structure parallel to [100].
