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

ABSTRACT: 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.

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.

catena-Poly[[bis-[aqua-(1,10-phenanthroline)lead(II)]-bis-(μ₃-2-hy-droxy-5-sulfonato-benzoato)] acetic acid monosolvate].

Project description:In the title compound, [Pb₂(C₇H₄O₆S)₂(C₁₂H₈N₂)₂(H₂O)₂]·CH₃COOH, the seven-coordinate Pb(II) atom is chelated by two N atoms of one 1,10-phenanthroline ligand, four O atoms from three 5-sulfosalicylate dianions and one water O atom. Each dianion serves as a bridging ligand, connecting adjacent Pb(II) atoms into a centrosymmetric polymeric chain extending parallel to [001]. There are π-π inter-actions between the aromatic systems of neighbouring dianions, with plane-to-plane distances of 3.371 (2) Å, and between phenanthroline ligands, with a centroid-to-centroid distance of 3.484 (2) Å. O-H⋯O hydrogen bonding additionally stabilizes the crystal packing. The acetic acid mol-ecules are incorporated in the voids of this arrangement. They exhibit half-occupancy due to disorder around a centre of inversion.

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-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.

Bis(μ-3-hydroxy-benzoato-κO,O':O)bis-[aqua-(3-hydroxy-benzoato-κO,O')(1,10-phenanthroline-κN,N')lead(II)] monohydrate.

Project description:In the centrosymmetric binuclear title complex, [Pb(2)(C(7)H(5)O(3))(4)(C(12)H(8)N(2))(2)(H(2)O)(2)]·H(2)O, each Pb atom is eight-coordinated in a PbO(6)N(2) environment by two N atoms from the 1,10-phenanthroline (phen) ligand, five carboxylate O atoms from four 3-hydroxy-benzoate anions and one O atom from the coordinated water mol-ecule in a distorted bicapped trigonal-prismatic geometry. The benzoate groups coordinate each Pb(II) atom in two different ways. Two benzoate ions behave as bidentate ligands to the Pb atom, and another benzoate ion bridges the Pb atoms, forming a binuclear structure. The dimeric units are packed via O-H⋯O hydrogen bonds and π-π inter-actions between the aromatic rings of neighboring mol-ecules, with centroid-centroid distances of 3.552 (2) and 3.641 (2) Å.

Bis(benzoato-?O,O')(2,2'-bipyridine-?N,N')lead(II) benzoic acid monosolvate.

Project description:The reaction of lead acetate, benzoic acid and 2,2'-bipyridine (bipy) in aqueous solution yielded the title complex, [Pb(C(7)H(5)O(2))(2)(C(10)H(8)N(2))]·C(7)H(6)O(2). The asymmetric unit contains two independent complex mol-ecules as well as two independent benzoic acid solvent mol-ecules, one of which is disordered over two positions with almost equal occupancies [0.504?(5) and 0.496?(5)]. The two complex mol-ecules have similar configurations with the hexa-coordinated environment of the Pb(II) atom formed by four carboxyl-ate O atoms of two chelate benzoate ligands and two N atoms of the bipy ligand. The Pb-O bonds involving one of the benzoate ligands are almost coplanar with Pb-N bonds to the bipy ligand [dihedral angles of 12.67?(11) and 14.73?(11)°] ; if the second benzoate ligand is treated as one coordination site, the overall coordination may be represented as a distorted pseudo-square pyramid. Weak inter-molecular Pb?O inter-actions [3.046?(3) and 3.359?(3)?Å] link each of the complex mol-ecules into two symmetry-independent centrosymmetric dimers. Hydrogen bonds involving the carboxyl H atoms of solvent benzoic acid mol-ecules and metal-coordinated carboxyl-ate O atoms link complex mol-ecules and benzoic acid solvent mol-ecules into insular aggregates.
