Bis(1H-imidazole-?N)bis-(2-methyl-benzoato-?O)bis-(2-methyl-benzoic acid-?O)copper(II).

ABSTRACT: The structure of the title compound, [Cu(C(8)H(7)O(2))(2)(C(3)H(4)N(2))(2)(C(8)H(8)O(2))(2)], consists of centrosymmetric monomeric units, in which the Cu(II) atom has a tetra-gonally distorted octa-hedral coordination involving two imidazole N atoms and two carboxyl-ate O atoms in the square plane [Cu-N = 1.964?(3) and Cu-O = 1.960?(2)?Å] and 2-methyl-benzoic acid O atoms in axial sites [Cu-O = 2.753?(3)?Å]. Within the complex, the carb-oxy-lic acid forms intra-molecular O-H?O hydrogen bonds, while the mol-ecules are assembled through N-H?O(carbox-yl) hydrogen bonds into chains extending along the a-axis direction. These chains are further linked by weak ?-? inter-actions [centroid-centroid separation = 3.930?(2)?Å].

Project description:In title compound, [Cu(C(8)H(7)O(2))(2)(C(6)H(6)N(4))(2)], the Cu(II) atom (site symmetry ) is coordinated by two N,N'-bidentate 2,2'-biimidazole ligands and two weakly bonded 4-methyl-benzoate anions, resulting in a strongly elongated trans-CuO(2)N(4) octa-hedral geometry.

Project description:In the title centrosymmetric dinuclear compound, [Cu(2)(C(8)H(7)O(2))(4)(C(8)H(8)O(2))(2)], four o-toluate anions form a cage around two Cu atoms in a syn-syn configuration. Two more o-toluic acid mol-ecules are apically bonded to the Cu atoms, which show a square-pyramidal coordination geometry. The acid H atoms are hydrogen bonded to the cage carboxyl O atoms [O⋯O = 2.660 (2) Å]. The mol-ecular packing forms a puckered pseudo-hexa-gonal close-packed layer in the (h00) plane, with soft inter-molecular H⋯H contacts (2.46-2.58 Å).

Project description:In the title compound, [Cu(C(7)H(5)O(2))(2)(C(3)H(4)N(2))(2)(H(2)O)]·H(2)O, the Cu(II) atom is in a distorted square-pyramidal environment. The mol-ecules are assembled into double chains extending along [010] by N-H⋯O hydrogen bonds. These double chains are linked by O-H⋯O hydrogen bonds, forming layers parallel to (02); the layers are linked into a three-dimensional network by van der Waals inter-actions.

Aqua-bis(1H-imidazole-?N)bis-(4-methyl-benzoato-?O,O')cadmium(II).

Project description:In the title compound, [Cd(C(8)H(7)O(2))(2)(C(3)H(4)N(2))(2)(H(2)O)], the Cd(II) atom is coordinated by four carboxyl-ate O atoms from two bidentate chelating 4-methyl-benzoate ligands, two N atoms from two imidazole ligands and one water mol-ecule in a distorted penta-gonal bipyramidal geometry. Inter-molecular O-H?O hydrogen bonds between the coordinated water mol-ecule and the carboxyl-ate O atoms of 4-methyl-benzoate lead to an infinite chain. These chains are further self-assembled into a two-dimensional layer through N-H?O hydrogen bonds between the imidazole ligands and carboxyl-ate groups. One of the imidazole ligands is disordered over two positions with site-occupancy factors of 0.737?(4) and 0.263?(4).

Diaqua-bis(2,2'-bi-1H-imidazole-κN,N)nickel(II) bis-(3-methyl-benzoate) 3-methyl-benzoic acid disolvate.

Project description:In the title compound, [Ni(C(6)H(6)N(4))(2)(H(2)O)(2)](C(8)H(7)O(2))(2)·2C(8)H(8)O(2), the Ni(II) atom (site symmetry ) is coordinated by two N,N'-bidentate 2,2'-biimidazole ligands and two water mol-ecules, resulting in a slightly distorted trans-NiO(2)N(4) geometry for the metal ion. In the crystal, the components are linked by N-H⋯O and O-H⋯O hydrogen bonds, generating an infinite two-dimensional network running parallel to (100). The methyl group of the benzoic acid mol-ecule is disordered over two sites in a 0.563 (17):0.437 (17) ratio.

(Benzoato-?O)bis-(1,10-phenanthroline-?N,N')copper(II) chloride benzoic acid disolvate.

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.
