Bis(3,5-dicarboxy-benzoato-κO,O')(1,10-phenanthroline-κN,N')cadmium(II).

ABSTRACT: The mol-ecule of the title compound, [Cd(C(9)H(5)O(6))(2)(C(12)H(8)N(2))], has crystallographic twofold rotation symmetry. The Cd(II) atom, located on the twofold axis, assumes a CdO(4)N(2) distorted octa-hedral coordination geometry. In the crystal structure, the mol-ecules link to each other by O-H⋯O and C-H⋯O hydrogen bonding to form a three-dimensional supra-molecular network.

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-2,4-dihy-droxy-benzoato-κO:O')bis-[aqua-(2,4-dihy-droxy-benzoato-κO)(1,10-phenanthroline-κN,N')cadmium(II)].

Project description:In the title centrosymmetric dimeric Cd(II) complex, [Cd(2)(C(7)H(5)O(4))(4)(C(12)H(8)N(2))(2)(H(2)O)(2)], the Cd(II) cation is coord-inated by a bidentate phenanthroline (phen) ligand, three dihy-droxy-benzoate (dhba) anions and one water mol-ecule in a distorted CdN(2)O(4) octa-hedral geometry. Among the dhba anions, two anions bridge two Cd(II) cations to form the dimeric complex with significant different Cd-O bond distances of 2.2215 (19) and 2.406 (2) Å. The centroid-centroid distance of 3.4615 (19) Å between two nearly parallel benzene rings of the dhba and phen ligands coordinating to the same Cd(II) cation indicates the existence of intra-molecular π-π stacking in the complex. Extensive O-H⋯O hydrogen bonding and inter-molecular weak C-H⋯O hydrogen bonding help to stabilize the crystal structure. One hy-droxy group of the monodentate dhba ligand is disordered over two sites with a site-occupancy ratio of 0.9:0.1.

Project description:In the binuclear title complex, [Dy(2)(C(7)H(3)N(2)O(6))(6)(C(12)H(8)N(2))(2)], the Dy(III) ions exhibit a distorted monocapped square-anti-prismatic geometry and are coordinated by seven O atoms of four 3,5-dinitrobenzoate (DNBA) anions and two N atoms of a phenanthroline ligand. The carboxylate groups of the DNBA anions exhibit three coordination modes: bidentate chelating, bidentate chelating-bridging and tridentate chelating-bridging. The center of the mol-ecule is located on a crystallographic center of inversion.

Di-μ-benzoato-κO,O':O';κO:O,O'-bis-[(benzoato-κO,O')(1,10-phenanthroline-κN,N')cadmium].

Project description:The dinuclear title compound, [Cd(2)(C(7)H(5)O(2))(4)(C(12)H(8)N(2))(2)], lies on a crystallographic twofold axis. The Cd(II) ions are connected by two bridging benzoate anions and each ion is seven-coordinated by five O atoms from three benzoate ligands and by two N atoms from 1,10-phenanthroline. The benzoate ligands adopt two different coordination modes, acting as bidentate and bridging tridentate ligands. The discrete neutral mol-ecules further extend their structure into a three-dimensional supra-molecular framework by inter-molecular π-π [inter-planar distances of 3.392 (4) Å] and C-H⋯π stacking inter-actions [H-mean plane = 2.567 (4) and 2.781 (4) Å].

Aqua-bis-(3-fluoro-benzoato-κO)(1,10-phenanthroline-κN,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 π-π stacking [centroid-centroid distance = 3.731 (2) Å] inter-actions consolidate the crystal packing.

Bis(2-methyl-benzoato-κO,O')(1,10'-phenanthroline-κN,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, π-π 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).

Project description:In the title compound, [Co(C(7)H(5)O(2))(2)(C(14)H(12)N(2))], the Co(II) ion is located on a twofold rotation axis and is chelated by a 2,9-dimethyl-1,10-phenanthroline (dmphen) ligand and two benzoate anions in a distorted octa-hedral geometry. The crystal packing is stabilized by π-π inter-actions between parallel dmphen ligands of neighbouring mol-ecules, with a face-to-face distance of 3.411 (2) Å.

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

Project description: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⋯π inter-actions result in chains of mol-ecules along the c axis.
