μ-Aqua-κO:O-di-μ-4-methyl-benzoato-κO:O'-bis-[(4-methyl-benzoato-κO)(1,10-phenanthroline-κN,N')nickel(II)].

ABSTRACT: In the title dinuclear complex, [Ni(2)(C(8)H(7)O(2))(4)(C(12)H(8)N(2))(2)(H(2)O)], each Ni(II) atom is six-coordinated by three carboxylate O atoms from three 4-methyl-benzoate ligands, two N atoms from two 1,10-phenanthroline ligands, and one μ(2)-bridging aqua ligand. The dimeric complex is located on a crystallographic twofold axis and each Ni atom displays a distorted octa-hedral coordination geometry. The crystal structure is stabilized via intra-molecular hydrogen bonding of the bridging water mol-ecule and the uncoordinated carboxyl-ate O atoms, and by C-H⋯O and π-π stacking inter-actions [centroid-centroid distances between neighbouring phenanthroline ring systems and between the benzene ring of a 4-methyl-benzoate unit and a phenanthroline ring system are 3.662 (2) and 3.611 (3) Å, respectively].

Project description:In the title binuclear complex, [Fe(2)(C(8)H(7)O(2))(4)(C(12)H(8)N(2))(2)(H(2)O)], the Fe(II) ion is six-coordinated by three carboxylate O atoms from three 4-methyl-benzoate ligands, two N atoms from two 1,10-phenanthroline ligands and one bridging aqua ligand in a distorted octa-hedral geometry.

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.

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].

Di-μ-benzoato-κO,O':O;κO:O,O'-bis-[(benzoato-κO,O')(1,10-phenanthroline-κN,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 π-π stacking inter-actions, with a shortest centroid-centroid distance of 3.617 (4) Å.

Aqua-bis-(benzoato-κO)(1,10-phenanthroline-κN,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.

Di-μ-glutarato-κO:O-bis-[aqua-(1,10-phenanthroline-κN,N')copper(II)].

Project description:In the centrosymmetric dinuclear title complex, [Cu(2)(C(5)H(6)O(4))(2)(C(12)H(18)N(2))(2)(H(2)O)(2)], the Cu(II) atom displays a dis-torted square-pyramidal coordination environment with the basal plane occupied by two phenanthroline N atoms and two O atoms from different glutarate dianions while a water mol-ecule is located at the apical position. Of the two water H atoms, one is engaged in an intra-molecular hydrogen bond with a free oxygen of the dianion whereas the second is engaged in an inter-molecular hydrogen bond, building a corrugated layer parallel to (100). These layers are further connected through π-π stacking inter-actions involving symmetry-related phenanthroline rings [centroid-centroid distance = 3.5599 (17) and 3.5617 (18) Å], building a three dimensionnal network. C-H⋯π inter-actions involving the phenanthroline ring system are also observed.

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.

Aqua-(3-fluoro-benzoato-κO)(3-fluoro-benzoato-κO,O')(1,10-phenanthroline-κN,N')cobalt(II).

Project description:In the title compound, [Co(C(7)H(4)FO(2))(2)(C(12)H(8)N(2))(H(2)O)], the Co(II) ion is coordinated by two O atoms from one 3-fluoro-benzoate (fb) ligand and one O atom from another fb ligand, two N atoms from the 1,10-phenanthroline ligand and a water mol-ecule in a distorted octa-hedral geometry. An intra-molecular O-H⋯O hydrogen bond occurs. Inter-molecular O-H⋯O hydrogen bonds link pairs of mol-ecules into centrosymmetric dimers. Weak inter-molecular C-H⋯O and C-H⋯F hydrogen bonds and π-π inter-actions between the aromatic rings [shortest centroid-centroid distance = 3.4962 (2) Å] further stabilize the crystal packing.

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

Project description:The title compound, [Pb(2)(CH(3)COO)(2)(C(7)H(5)O(2))(2)(C(12)H(8)N(2))(2)]·2H(2)O, consists of dimeric units built up around a crystallographic centre of symmetry and two non-coordinating water mol-ecules. Each Pb(II) unit is six-coordinated by a bidentate 1,10-phenanthroline (phen) ligand, a monodentate acetate anion and a bidentate benzoate anion, which also acts as a bridge linking the two Pb(II) atoms. The crystal packing is stabilized by O-H⋯O hydrogen bonds and by π-π inter-actions between the phen rings of neighboring mol-ecules, with a centroid-centroid distance of 3.577 (3) 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.
