(2,2'-Bipyridine-?(2)N,N')bis-(4-formyl-benzoato-?O(1))copper(II).

ABSTRACT: The title mononuclear Cu(II) complex, [Cu(C(8)H(5)O(3))(2)(C(10)H(8)N(2))], is comprised of a Cu(II) cation, two 4-formyl-benzoate (L(-)) ligands and a 2,2'-bipyridine (bipy) ligand. The Cu(II) ion and bipy ligand lie on a crystallographic twofold rotation axis; the Cu(II) ion is coordinated by two N atoms from one bipy ligand and two O atoms from two different carboxyl-ate groups of two L(-) ligands, exhibiting effectively a distorted square-planar geometry. The complex mol-ecules are inter-linked to generate two-dimensional supra-molecular layers in the ab plane, formed by C-H?O hydrogen bonds, where the O acceptor is the O atom from the carboxyl-ate group not involved in coordination to the Cu(II) ion. The two-dimensional layers are stacked in a sequence via C-H?O hydrogen-bonding inter-actions where the formyl O atom acts as acceptor.

Project description:The Cu(II) atom in the title compound, [Cu(C(7)H(4)IO(2))(2)(C(10)H(8)N(2))(H(2)O)], is N,N'-chelated by a 2,2'-bipyridine ligand and is coordinated by two monodentate carboxyl-ate ions and a water mol-ecule in a distorted square-pyramidal geometry. The apical site is occupied by one of the carboxyl-ate O atoms. The water mol-ecule forms intra-molecular hydrogen bonds to the uncoordinated carboxyl O atoms. The crystal studied was a nonmerohedral twin with minor components in 0.381?(3) and 0.108?(2) proportions.

Bis(2,2'-bipyridine-?N,N')(4-methyl-benzoato-?O,O')copper(II) iodide hemihydrate.

Project description:The title compound, [Cu(C(8)H(7)O(2))(C(10)H(8)N(2))(2)]I·0.5H(2)O, was obtained by the hydro-thermal reaction of copper(I) iodide, 4-methyl-benzoic acid and 2,2'-bipyridine. The initial reactant of Cu(I) was oxidized to Cu(II). The asymmetric unit contains two independent complex mol-ecules, two I(-) ions and one water molecule. Each Cu(II) atom is coordinated by two O atoms from a 4-methyl-benzoate ligand and four N atoms from two 2,2'-bipyridine ligands, displaying a distorted octa-hedral geometry. The structure involves O-H?I hydrogen bonds between the water mol-ecule and iodide ions and ?-? stacking inter-actions between the benzene and pyridyl rings [centroid-centroid distance = 3.79?(1)?Å] and between the pyridyl rings [centroid-centroid distance = 3.87?(1)?Å].

Bis(?-biphenyl-2,2'-dicarboxyl-ato)bis-[(2,2'-bipyridine)copper(II)].

Project description:The title compound, [Cu(2)(C(14)H(8)O(4))(2)(C(10)H(8)N(2))(2)], is a centrosymmetric binuclear copper(II) complex, with a Cu?Cu separation of 6.136?(16)?Å. The Cu atom displays a cis-CuN(2)O(2) square-planar geometry, although two long (> 2.43?Å) Cu?O contacts complete a distorted cis-CuN(2)O(4) octa-hedron. Extensive C-H?O hydrogen bonds link the mol-ecules into a three-dimensional network.

Aqua-(2,2'-bipyridine)bis-(4-hydroxy-benzoato)zinc(II).

Project description:In the title complex, [Zn(C(7)H(5)O(3))(2)(C(10)H(8)N(2))(H(2)O)], the Zn(II) ion is coordinated by two 4-hydroxy-benzoate anions, one 2,2'-bipyridine mol-ecule and one water mol-ecule and displays a distorted octa-hedral geometry. One Zn-O bond [2.5300?(15)?Å] is much longer than the others in the mol-ecule. In the crystal structure, the face-to-face separation of 3.547?(9)?Å suggests no ?-? stacking between parallel bipyridine ring systems, and an extensive O-H?O hydrogen-bonding network between the coordinated water molecule, the phenol group and carboxylate O atoms is present.

(2,2'-Bipyridine-κN,N')bis-(3-meth-oxy-benzoato-κO,O)copper(II) mono-hydrate.

Project description:The title compound, [Cu(C(8)H(7)O(3))(2)(C(10)H(8)N(2))]·H(2)O, is comprised of a Cu(II) ion, two 3-meth-oxy-benzoate ligands, a 2,2'-bipyridine (bipy) ligand and one uncoordinated water mol-ecule. The Cu(II) ion and the water O atom lie on a twofold axis. The Cu(II) ion exhibits a six-coordinate distorted octa-hedral geometry, with two N atoms from the bipy ligand [Cu-N = 1.9996 (16) Å] and four O atoms from two 3-meth-oxy-benzoate ligands [Cu-O = 1.9551 (15) and 2.6016 (16) Å].

Bis(μ-biphenyl-2,2'-dicarboxyl-ato)bis-[(2,2'-bipyridine)copper(II)].

Project description:The title compound, [Cu(2)(C(14)H(8)O(4))(2)(C(10)H(8)N(2))(2)], was obtained by solvothermal synthesis. The Cu(II) atom is coordinated by one chelating 2,2'-bipyridine ligand and two carboxyl groups from different biphenyl-2,2'-dicarboxyl-ate ligands, leading to a distorted octahedral environment. Each carboxyl-ate group makes one short Cu-O bond [1.9608 (14) and 1.9701 (14) Å] and one longer Cu-O contact [2.4338 (17) and 2.5541 (17) Å] to each Cu(II) atom. The biphenyl-2,2'-dicarboxyl-ate ligands bridge between Cu(II) atoms, forming a dinuclear complex around a crystallographic inversion centre.

Project description:In the title compound, [Pb(C(8)H(7)O(2))(2)(C(10)H(8)N(2))], the Pb(II) ion is coordinated by two N atoms from one 2,2'-bipyridine ligand and four O atoms from two 4-methyl-benzoate anions in a distorted pseudo-square-pyramidal environment, considering one of the carboxyl-ate anions as an apical ligand. Pairs of complex mol-ecules related by inversion centers are organized into dimers via pairs of Pb?O inter-actions [3.185?(2)?Å] and stacking interactions between 2,2'-bipyridine and 4-methyl-benzoate ligands, with a mean distance between their planes of 3.491?Å.

Diaqua-(2,2'-bipyridine-?N,N')bis-(perchlorato-?O)copper(II).

Project description:The central CuN(2)O(4) motif of the title compound, [Cu(ClO(4))(2)(C(10)H(8)N(2))(H(2)O)(2)], exhibits a Jahn-Teller-distorted octa-hedral geometry around the metal atom, showing a considerably long Cu-O bond distance of 2.5058?(12)?Å towards the second perchlorate group, giving a (4 + 1+1)-type coordination mode. In the crystal, the components are linked via inter-molecular O-H?O hydrogen bonds, forming layers parallel to (001). Additional stabilization within these layers is provided by ?-? [centroid-centroid distances of 3.7848?(9)-4.4231?(9)?Å] stacking inter-actions.
