Catena-Poly[μ-aqua-2:1'κO:O-aqua-2κO-(2-fluoro-benzoato-1κO,O')(μ(2)-2-fluoro-benzoato-2':1κO:O')bis-(μ(3)-2-fluoro-benzoato)-2':1:2κO:O,O':O';1:2:1'κF,O:O,O':O'-dilead(II)].

ABSTRACT: In the title compound, [Pb(2)(C(7)H(4)FO(2))(4)(H(2)O)(2)](n), one Pb(II) atom is coordinated by seven O atoms and one F atom from five 2-fluoro-benzoate ligands, and the other Pb(II) atom is coordinated by five O atoms from four 2-fluoro-benzoate ligands and three water mol-ecules, resulting in distorted PbO(7)F and PbO(8) polyhedra. The 2-fluoro-benzoate ligands bridge Pb atoms, giving rise to a one-dimensional chain structure extending along the [100] direction. The polymeric chains are connected via C-H⋯O hydrogen bonds and π-π inter-actions, with an inter-planar distance of 3.46 (1) Å. An intramolecular O-H⋯F interaction is also present.

Project description:In title compound, [Ca(C(7)H(5)O(2))(2)(C(7)H(6)O(2))(H(2)O)](n), the eightfold-coordinated Ca(II) ion is bonded to four carboxyl-ate O atoms from two benzoate ions, an O atom from benzoic acid and a water O atom. One of the carboxyl-ate groups bridges adjacent Ca(2+) ions, forming a polymeric ribbon structure parallel to [010]. In the crystal, the benzoate anions and water mol-ecule inter-act by way of inter- and intra-molecular O-H⋯O hydrogen bonds.

catena-Poly[[diaqua-cobalt(II)]-bis-(μ-4-fluoro-benzoato-κO:O')].

Project description:The hydro-thermal reaction of CoCO(3) and 4-fluoro-benzoic acid afforded the title Co(II) complex, [Co(C(7)H(4)FO(2))(2)(H(2)O)(2)](n). The Co(II) atom is located on an inversion center and is coordinated by six O atoms from two water mol-ecules and four μ(2)-carboxyl-ate groups of 4-fluoro-benzoate anions, forming a distorted CoO(6) octa-hedron, with Co-O bond lengths in the range 2.071 (2)-2.130 (2) Å. All adjacent O-Co-O angles are in the range 84.78 (6)-95.22 (6)° and opposite angles are 180.0°. Each μ-carboxyl-ate group of the 4-fluoro-benzoate anions bridges two symmetry-related Co(II) atoms. Hydrogen-bonding inter-actions of the coordinated water mol-ecules further connect the cobalt-carboxyl-ate units, forming layers perpendicular to the a axis. The cobalt-oxygen layers are encased in a sandwich-like fashion by layers of π-stacked 4-fluoro-benzoate anions. Within these layers the benzene rings of the 4-fluoro-benzoate anions are π-stacked, with centroid-centroid distances of 3.432 (4) Å.

catena-Poly[[aqua-(4-ethyl-benzoic acid-κO)lanthanum(III)]-tri-μ-4-ethyl-benzoato].

Project description:The reaction of lanthanum nitrate and 4-ethyl-benzoic acid (EBAH) in aqueous solution yielded the title polymer, [La(C(9)H(9)O(2))(3)(C(9)H(10)O(2))(H(2)O)](n). The asymmetric unit contains one La(III) atom, three 4-ethyl-benzoate (EBA) ligands, one neutral EBAH ligand and one coordinated water mol-ecule. Each La(III) ion is eight-coordinated by six O atoms from six bridging-bidentate EBA ligands, one O atom from a monodentate EBAH ligand and one water O atom in a distorted bicapped trigonal-prismatic geometry. The adjacent La(III) ions are linked by the carboxyl-ate groups of EBA ligands in a bridging-bidetate coordination mode, resulting in an infinite chain structure along the c axis. O-H⋯O hydrogen-bonding inter-actions involving the water mol-ecules, carboxyl-ate groups and carboxyl H atoms are formed within the one-dimensional polymer. One of the ethyl groups is disordered over two positions with occupancies of 0.717 (7) and 0.283 (7).

catena-Poly[[tetra-kis-(μ-penta-fluoro-benzoato-κO:O')dimolybdenum(II)]-μ-4,4'-bipyridine-κN:N'].

Project description:In the title compound, [Mo(2)(C(7)F(5)O(2))(4)(C(10)H(8)N(2))](n), the mol-ecule forms a paddle-wheel-type structure. Each Mo(2) (4+) unit is equatorially coordinated by four pentafluoro-benzoate groups, while the axial positions are occupied by two 4,4'-bipyridine mol-ecules. The Mo-Mo bond length of 2.1227 (4) Å is representative of a dimolybdenum quadruple bond. An infinite linear chain parallel to [110] is formed by the Mo(2) (4+) unit coordinating axially to the two N atoms of the 4,4'-bipyridine ligand [Mo-N = 2.594 (2) Å]. The crystal packing shows mol-ecules linked together into a three-dimensional network via Mo-N coordination inter-actions and weak π-π stacking inter-actions between perfluoro-phenyl rings [centroid-centroid distance = 3.7280 (3) Å and centroid-to-plane distance = 3.6103 (12) Å between two penta-fluoro-phenyl rings].

Project description:The asymmetric unit of the title complex, [Mn(2)(C(8)H(7)O(2))(4)(C(10)H(14)N(2)O)(2)(H(2)O)](n), contains two crystallographically independent units. In each one, the Mn(II) ions are bridged by two 4-methyl-benzoate (PMB) ligands and one water mol-ecule. In the crystal structure, each Mn(II) ion is coordinated by three PMB ligands, one water mol-ecule and two symmetry-related N,N-diethyl-nicotinamide (DENA) ligands. Symmetry-related Mn(II) ions are bridged by the N and O atoms of symmetry-related DENA ligands, forming polymeric chains parallel to [100]. The coord-ination environmnts for the Mn(II) ions are slightly distorted octa-hedral. Intra-molecular O-H⋯O hydrogen bonds link bridging water mol-ecules to the carboxyl-ate O atoms of a neigh-boring polymeric chain. In the crystal structure, π-π contacts between benzene rings [centroid-centroid distance = 3.562 (1) Å] and weak C-H⋯π inter-actions are also observed.

Crystal structure of catena-poly[[[di-aqua-bis-(2,4,6-tri-methyl-benzoato-κO)cobalt(II)]-μ-aqua-κ2O:O] dihydrate].

Project description:The asymmetric unit of the title one-dimensional polymeric compound, {[Co(C10H11O2)2(H2O)3]·2H2O} n , contains one CoII cation situated on a centre of inversion, one-half of a coordinating water mol-ecule, one 2,4,6-tri-methyl-benzoate (TMB) anion together with one coordinating and one non-coordinating water mol-ecule; the TMB anion acts as a monodentate ligand. In the anion, the carboxyl-ate group is twisted away from the attached benzene ring by 84.9 (2)°. The CoII atom is coordinated by two TMB anions and two water mol-ecules in the basal plane, while another water mol-ecule bridges the CoII atoms in the axial directions, forming polymeric chains running along [001]. The coordination environment for the CoII cation is a slightly distorted octa-hedron. The coordinating and bridging water mol-ecules link to the carboxyl-ate groups via intra- and inter-molecular O-H⋯O hydrogen bonds, enclosing S(6) ring motifs, while the coordinating, bridging and non-coordinating water mol-ecules link to the carboxyl-ate groups and the coordinating water mol-ecules link to the non-coordinating water mol-ecules via O-H⋯O hydrogen bonds, enclosing R22(8) and R33(8) ring motifs. Weak C-H⋯O and C-H⋯π inter-actions may further stabilize the crystal structure.

Project description:In the title polymeric complex, [Cu(2)(C(6)H(8)O(4))(2)(C(3)H(7)NO)(2)](n), the carboxyl-ate groups of the approximately U-shaped adipate dianion each bridge a pair of inversion-related, DMF-coordinated copper(II) atoms, generating a ribbon motif that runs along the b axis. The geometry of the copper(II) atom is distorted square-pyramidal; the apical site is occupied by the O atom of the DMF mol-ecule whereas the four basal sites are occupied by carboxyl-ate O atoms.
