Bis(3,4-dimethoxy-benzoato-?O,O')(1,10-phenanthroline-?N,N')copper(II).

ABSTRACT: The asymmetric unit of the title compound, [Cu(C(9)H(9)O(4))(2)(C(12)H(8)N(2))], contains one half-mol-ecule, the complete mol-ecule being generated by a twofold rotation axis. The Cu(II) atom exhibits a six-coordinated distorted octa-hedral geometry with two N atoms from the phenanthroline ligand [Cu-N 2.007?(2)?Å] and four O atoms from two 3,4-dimethoxy-benzoate ligands [Cu-O 1.950?(1) and 2.524?(1)?Å]. The difference in Cu-O bond distances indicates a strong Jahn-Teller effect. In the crystal, C-H?? inter-actions result in chains of mol-ecules along the c axis.

Tetra-kis(?-3,4-dimethoxy-phenyl-acetato)bis-[(3,4-dimethoxy-phenyl-acetato)(1,10-phenanthroline)dysprosium(III)].

Project description:The title centrosymmetric dinuclear dysprosium(III) complex, [Dy(2)(C(10)H(11)O(4))(6)(C(12)H(8)N(2))(2)] or [Dy(L)(3)phen](2), is comprised of six 3,4-dimethoxy-phenylacetate (L) anions, two 1,10-phenanthroline (phen) mol-ecules and two Dy(III) ions. The Dy(III) atom is nine-coordinated by seven O atoms from five L ligands and two N atoms from the phen mol-ecules. The L ligands are coordinated to the Dy(III) ion in three coordination modes: chelating, bridging and bridging-tridentate. C-H?O hydrogen bonding interactions consolidate the crystal packing.

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.

Bis(2-methyl-benzoato-?O,O')(1,10'-phenanthroline-?N,N')copper(II).

Project description:In the title compound, [Cu(C(8)H(7)O(2))(2)(C(12)H(8)N(2))], the Cu(II) atom assumes a distorted octa-hedral coordination geometry, chelated by two N atoms from the 1,10'-phenanthroline ligand and four O atoms from two 2-methyl-benzoate anions. A significant Jahn-Teller distortion is observed with two axial Cu-O distances significantly longer than those in the equatorial CuO(2)N(2) plane. In the crystal, ?-? stacking inter-actions, with centroid-centroid distances of 3.547?(3) or 3.728?(3)?Å between the phenanthroline rings, form layers parallel to (011).

(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.

(2,9-Dimethyl-1,10-phenanthroline-κN,N')bis-(2-hydroxy-benzoato-κO)copper(II).

Project description:The Cu(II) atoms in the two independent mol-ecules of the title compound, [Cu(C(7)H(5)O(3))(2)(C(14)H(12)N(2))], are each coordinated by a bidentate 2,9-dimethyl-1,10-phenanthroline (dmphen) mol-ecule and two monodentate 2-hydroxy-benzoate anions in a distorted tetra-hedral geometry. The crystal packing is stabilized by intra-molecular hydrogen bonding and π-π inter-actions between the dmphen rings of neighboring mol-ecules, with distances between their ring planes of 3.5670 (4) and 3.5181 (9) 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.

Diaqua-bis-(perchlorato)(1,10-phenanthroline)copper(II).

Project description:In the title compound, [Cu(ClO(4))(2)(C(12)H(8)N(2))(H(2)O)(2)], the Cu(II) atom is coordinated in a square-planar fashion by the two N atoms of a chelating 1,10-phenanthroline ligand and by two water mol-ecules trans to the N atoms. The coordination sphere of the metal atom is augmented by O atoms of two weakly bonded perchlorate anions, thus yielding a strongly distorted CuN(2)O(4) octa-hedral environment. The crystal packing is stabilized by O-H⋯O hydrogen bonds between the water mol-ecules and the perchlorate anions. In addition, the organic mol-ecules are associated by π-π stacking inter-actions between symmetry-equivalent anti-parallel non-nitro-gen aromatic rings, with inter-planar distances of 3.543 (2) 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.

The Cu(II) ion adopts a distorted square-pyramidal geometry formed by two N atoms from the 1,10-phenanthroline ligand and two O atoms of the two 4-amino-benzoic acid ligands and one water O atom. The Cu⋯Cu separation is 3.109 (2) Å. A twofold axis passes through the mid-point of the Cu⋯Cu vector.

Project description:In the title mononuclear complex, [Cu(C(8)H(7)O(2))Cl(C(12)H(8)N(2))(H(2)O)], the Cu(II) atom is coordinated by one carboxylate O atom from a monodentate 4-methyl-benzoate ligand, two N atoms from the 1,10-phenanthroline ligand, one chloride ion and one water mol-ecule in a square-pyramidal geometry.
