catena-Poly[bis-(?(3)-2-methyl-3,5-dinitro-benzoato)disilver(I)].

Project description:In the title coordination polymer, [Ag(2)(C(8)H(5)N(2)O(6))(2)](n), the silver ion is coordinated to three O atoms from three different anions in an approximate T-shape with one bond much longer than the other two. The polyhedral connectivity leads to [100] chains containing alternating centrosymmetric four-rings and eight-rings, with a short d(10)?d(10) Ag?Ag interaction [2.8846?(4)?Å] across the latter. The nitro groups are oriented at dihedral angles of 21.2?(5) and 64.3?(3)° with respect to the aromatic ring of the ligand. A C-H?O inter-action occurs in the crystal.

catena-Poly[(diaqua-strontium)-bis-(μ-2-methyl-3,5-dinitro-benzoato)].

Project description:The title compound, [Sr(C(8)H(5)N(2)O(6))(2)(H(2)O)(2)](n), essentially consists of a one-dimensional polymeric network with Sr(2)O(2) rings extending along the [100] direction. The range of Sr-O bond lengths is 2.4822 (13)-2.8113 (13) Å. C-H⋯O and O-H⋯O hydrogen-bonding inter-actions stabilize the mol-ecules in the form of a two-dimensional polymeric network parallel to (001). One of the nitro groups is disordered over three sets of sites with the occupancy ratio of 0.46:0.32:0.22.

catena-Poly[bis-(?-4-methyl-benzoato-?O:O')hepta-kis(?-4-methyl-benzoato-?O,O':O)tris-amarium(III)].

Project description:The title samarium coordination polymer, [Sm(3)(C(8)H(7)O(2))(9)](n), was obtained by the hydro-thermal reaction of Sm(NO(3))(3) with 4-methyl-benzoic acid in alkaline aqueous solution. In the asymmetric unit, there are three crystallographically independent Sm(III) ions, two of which are eight-coordinate in a distorted square-anti-prismatic environment, while the third is nine-coordinate in a distorted tricapped trigonal-prismatic coordination. The metal centres are coordinated and bridged by four tridentate, three bidentate and two monodentate methyl-benzoate anions, forming polymeric chains running parallel to the b axis.

catena-Poly[[bis-(3-methyl-benzoato-?O,O')lead(II)]-?-4,4'-bipyridine-?N:N'].

Project description:In the title complex, [Pb(C(8)H(7)O(2))(2)(C(10)H(8)N(2))](n), the Pb(II) atom is located on a twofold rotation axis and is six-coordinated by four carboxyl-ate O atoms from two 3-methyl-benzoate ligands and two N atoms from two 4,4'-bipyridine (4,4'-bpy) ligands, displaying a hemi-directed coordination. The 4,4'-bpy ligand has an inversion center at the mid-point of the central C-C bond. The Pb(II) atoms are linked by bidentate bridging 4,4'-bpy into a chain along [101]. These chains are further connected into layers via C-H?O hydrogen bonds.

Project description:In the title compound, [Pb(C(8)H(7)O(2))(2)(C(6)H(6)N(2)O)](n), the Pb(II) ion is coordinated by two 4-methyl-benzoate (PMB) and one nicotinamide (NA) ligands while symmetry-related NA ligands bridge adjacent Pb(II) ions, forming polymeric chains along the c axis. The carboxyl-ate groups in the two PMB ions are twisted away from the attached benzene ring by 22.9 (2) and 4.6 (2)°. The two benzene rings of the PMB ions are oriented at a dihedral angle of 83.7 (1)°. In a polymeric chain, the NA ligands are linked to PMB ions through intra-molecular N-H⋯O hydrogen bonds. In the crystal structure, adjacent polymeric chains inter-act via N-H⋯O and C-H⋯O hydrogen bonds, forming a two-dimensional network parallel to the bc plane.

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.

catena-Poly[[[bis-(4-methyl-benzoato-?O,O')zinc(II)]-?-4,4'-bipyridine-?N:N'] tetra-hydrate].

Project description:The asymmetric unit of the title compound, {[Zn(C(7)H(7)O(2))(2)(C(10)H(8)N(2))]·4H(2)O}(n), contains a highly distorted octa-hedral Zn(II) metal center strongly coordinated by two N atoms of two 4,4'-bipyridine (4,4'-bipy) ligands and chelated by two 4-methyl-benzoate anions. The crystallographic inversion center and glide plane present at the center of the C-C single bond of 4,4'-bipy, along with the cis coordination motif of the 4,4'-bipy, lead to one-dimensional zigzag chains. There are a large number of water mol-ecules in the crystal structure, which also form one-dimensional chains through O-H?O hydrogen bonds.

catena-Poly[[bis-(5-chloro-2-nitro-benzoato)copper(II)]-bis-(?-5-chloro-2-nitro-benzoato)].

Project description:In the title compound, [Cu(2)(C(7)H(3)ClNO(4))(4)](n), the coordination geometry around each Cu(II) ion is distorted square-pyramidal. The CuO(5) coordination is formed by five O atoms from the carboxyl-ate groups of five 5-chloro-2-nitro-benzoate ligands. This coordination leads to the formation of centrosymmetric binuclear units which are edge-shared, forming a linear chain along the a axis, with the Cu(II) ions alternately separated by 2.5891?(4) and 3.1763?(4)?Å. The chains are inter-connected into a three-dimensional network by C-H?O inter-actions.

catena-Poly[[[diaqua-cadmium(II)]-bis-[μ-3,5-bis-(isonicotinamido)benzoato]] tetra-hydrate].

Project description:The title compound, {[Cd(C(19)H(13)N(4)O(4))(2)(H(2)O)(2)]·4H(2)O}(n) or {[Cd(BBA)(2)(H(2)O)(2)]·4H(2)O}(n), where BBA is 3,5-bis-(iso-nicotin-amido)-benzoate, is isotypic with its Mn isologue [Chen et al. (2009 ▶). J. Coord. Chem.62, 2421-2428]. The cation sits on a twofold axis and is six-coordinated in a slightly distorted octa-hedral geometry; the polyhedra are linked into zigzag chains, which are further connected by N-H⋯O, O-H⋯O and O-H⋯N hydrogen bonds as well as π-π inter-actions [centroid-centroid distance of 3.639 (2) Å], giving a three-dimensional supra-molecular framework.

catena-Poly[[aqua-(3-methyl-benzoato-?O,O')lead(II)]-?-3-methyl-benzoato-?O:O,O':O'].

Project description:The reaction of lead(II) acetate and 3-methyl-benzoic acid (MBA) in aqueous solution yielded the title polymer, [Pb(C(8)H(7)O(2))(2)(H(2)O)](n). The asymmetric unit contains two Pb(II) atoms, four MBA ligands and two water mol-ecules. Each Pb(II) cation is hepta-coordinated and chelated by four carboxyl-ate O atoms from two MBA ligands. The Pb atoms are bridged through the carboxyl-ate O atoms from another two MBA ligands, leading to a central Pb(2)O(2) core. The Pb-O bond lengths are in the range 2.325?(3)-2.757?(4)?Å. The intra- and inter-dimer Pb?Pb distances are 4.2942?(3) and 4.2283?(3)?Å, respectively, indicating little direct metal-metal inter-action. The coordinating water mol-ecules and carboxyl-ate O atoms are involved in extensive O-H?O hydrogen-bonding inter-actions. The complex has an extended ladder-like chain structure and the chains are assembled by hydrogen bonds and ?-? inter-actions [centroid-centroid distance = 3.6246?(3)?Å] into a three-dimensional supra-molecular structure.
