Poly[(μ(5)-2,6-dimethyl-pyridine-3,5-dicarboxyl-ato)zinc].

ABSTRACT: In the polymeric title complex, [Zn(C(9)H(7)NO(4))](n), the Zn(II) cation is located on a twofold rotation axis and is coordinated by five 2,6-dimethyl-pyridine-3,5-dicarboxyl-ate (mpdc) anions in a distorted ZnNO(4) trigonal-bipyramidal geometry. The mpdc anion is also located on the twofold rotation axis and bridges five Zn(II) cations, forming the three-dimensional polymeric complex. Weak C-H⋯π inter-actions are present in the crystal structure.

Project description:In the title coordination polymer, [Cu(C(9)H(8)NO(4))(2)](n), the Cu atom, located on a twofold rotation axis, is four coordinate in a distorted square-planar environment. Each 2,6-dimethyl-pyridinium-3,5-dicarboxyl-ate anion bridges two Cu atoms, forming a two-dimensional coordination polymer. A three-dimensional supra-molecular network is built from N-H⋯O hydrogen bonds involving the pyridinium NH and the carboxyl COO groups.

Poly[[tetra-aqua-bis-(μ(3)-pyridine-2,6-dicarboxyl-ato)(μ(2)-pyridine-2,6-dicarboxyl-ato)dilanthanum(III)] dihydrate].

Project description:There are two independent La(III) cations in the polymeric title compound, {[La(2)(C(7)H(3)NO(4))(3)(H(2)O)(4)]·2H(2)O}(n). One is nine-coordinated in an LaN(2)O(7) tricapped trigonal-prismatic geometry formed by three pyridine-2,6-dicarboxyl-ate anions and two water mol-ecules, while the other is ten-coordinated in an LaNO(9) bicapped square-anti-prismatic geometry formed by four pyridine-2,6-dicarboxyl-ate anions and two water mol-ecules. The two La(III) cations are separated by a non-bonding distance of 5.026 (3) Å. The pyridine-2,6-dicarboxyl-ate anions bridge the La(III) cations, forming a three-dimensional polymeric complex. The crystal structure contains extensive classical O-H⋯O hydrogen bonds and weak inter-molecular C-H⋯O hydrogen bonds. The crystal structure is further consolidated by π-π stacking between pyridine rings, the shortest centroid-centroid distance between parallel pyridine rings being 3.700 (5) Å.

Poly[piperazinediium [[aqua-bismuth-ate(III)]-di-μ-pyridine-2,6-dicarboxyl-ato-bis-muthate(III)-di-μ-pyridine-2,6-dicarboxyl-ato] monohydrate].

Project description:The title compound, {(C(4)H(12)N(2))[Bi(2)(C(7)H(3)NO(4))(4)(H(2)O)]·H(2)O}(n) or {(pipzH(2))[Bi(2)(pydc)(4)(H(2)O)]·H(2)O}(n), where pydcH(2) is pyridine-2,6-dicarboxylic acid and pipz is piperazine, was obtained by reaction of Bi(NO(3))(3)·5H(2)O with (pipzH(2))(pydc-H)(2)·3H(2)O in a 1:2 molar ratio in aqueous solution. There are two independent Bi(III) atoms in the structure, one of which is eight-coordinate with a distorted bicapped trigonal-prismatic geometry, and another which is nine-coordinate with a distorted tricapped trigonal-prismatic geometry. The carboxyl-ate groups of the (pydc)(2-) ligands link dinuclear [Bi(2)(C(7)H(3)NO(4))(4)(H(2)O)](2-) units into one-dimensional coordin-ation polymers. The pipzH(2) (2+) cations (site symmetry ) and non-coordinated water mol-ecules lie between these polymers, forming N-H⋯O and O-H⋯O hydrogen bonds to the O atoms of the carboxylate groups.

Poly[triaqua-μ(4)-pyridine-3,5-dicarboxyl-ato-barium(II)].

Project description:The reaction of the proton-transfer compound (pdaH(2))(py-3,5-dc)·H(2)O (pda = propane-1,3-diamine and py-3,5-dcH(2) = pyridine-3,5-dicarboxylic acid) with Ba(NO(3))(2) leads to the formation of the title polymeric compound, [Ba(C(7)H(3)NO(4))(H(2)O)(3)](n). The Ba(II) atom is nine-coordinated by six carboxyl-ate O atoms from the (py-3,5-dc)(2-) ligands, and three O atoms from the coordinated water mol-ecules. The coordination polyhedron around the Ba(II) atom is best described as tricapped trigonal-prismatic. In the crystal structure, inter-molecular inter-actions, such as X-H⋯O hydrogen bonds (X = O and C) and π-π stacking [centroid-centroid distances between pyridine rings of 3.6191 (13) and 3.6192 (13) Å] play an important role in stabilizing the supramolecular structure.

Poly[diaqua-[μ6-4,4'-(1,4-phenyl-ene)bis-(2,6-dimethyl-pyridine-3,5-dicarboxyl-ato)]dilead(II)].

Project description:The asymmetric unit of the title Pb-based coordination polymer, [Pb2(C24H16N2O8)(H2O)2] n , consists of one Pb(II) cation, half of a 4,4'-(1,4-phenyl-ene)bis-(2,6-dimethyl-pyridine-3,5-di-carb-oxyl-ate (L (4-)) ligand and one coordinating water mol-ecule. The centers of the benzene ring of the ligand and the four-membered Pb/O/Pb/O ring are located on centers of inversion. The Pb(II) ion is coordinated in form of a distorted polyhedron by seven O atoms from four separate L (4-) ligands and by one water O atom. The PbO7 polyhedra share O atoms, forming infinite zigzag [PbO4(H2O)] n chains along [100] that are bridged by L (4-) ligands, forming a two-dimensional coordination network parallel to (001). O-H⋯O hydrogen bonds involving the water mol-ecule are observed.

Poly[tetra-aqua-μ(3)-pyridine-3,5-dicarboxyl-ato-strontium(II)].

Project description:The reaction of strontium(II) nitrate with the proton-transfer compound (pdaH(2))(py-3,5-dc)·H(2)O (where pda = propane-1,3-diamine and py-3,5-dcH(2) = pyridine-3,5-dicarboxylic acid) leads to the formation of the title polymeric compound, [Sr(C(7)H(3)NO(4))(H(2)O)(4)](n). The propane-1,3-diaminium cation is not incorporated in this crystal structure. The Sr(II) atom lies on an inversion centre and is eight-coordinated by four O atoms from three py-3,5-dc ligands and four O atoms from four coordinated water mol-ecules. The coordination polyhedron of the Sr(II) atom is a distorted dodeca-hedron. These binuclear units are connected via the carboxyl-ate O atoms to build a one-dimensional polymeric chain. In the crystal structure, non-covalant inter-actions consisting of hydrogen bonds (X-H⋯O, with X = O and C) and π-π stacking inter-actions [3.4604 (19) Å] connect the various components to form a supra-molecular structure.

Project description:The asymmetric unit of the title compound, [Ce(2)(C(7)H(3)NO(4))(3)(H(2)O)(3)](n), contains two Ce(III) cations, three pyridine-3,5-dicarboxyl-ate (pyd) anions and three coordinated water mol-ecules. One Ce(III) cation is coordinated by seven carboxyl-ate O atoms from six pyd anions and two water mol-ecules in a square-face-capped square-anti-prismatic geometry. Another Ce(III) cation is coordinated by seven O atoms from six pdy anions and one water mol-ecule in a bicapped trigonal-prismatic geometry. The pdy anions bridge the Ce(III) cations, forming the three-dimensional polymeric structure. The crystal structure contains extensive O-H⋯O, O-H⋯N and weak C-H⋯O hydrogen bonds. π-π stacking is present in the crystal structure, the shortest centroid-centroid distance between parallel pyridine rings being 3.509 (4) Å.

Project description:The title compound, {(C(10)H(10)N(2))[Ce(2)(C(7)H(3)NO(4))(4)(H(2)O)(4)]·5H(2)O}(n), is composed of a one-dimensional anionic complex, a doubly protonated 4,4'-bipyridine mol-ecule as a counter-ion and five uncoordinated water mol-ecules. The anion bears two nine-coordinate Ce(III) ions, each with a distorted tricapped trigonal-prismatic geometry. In the crystal, inter-molecular C-H⋯O, N-H⋯O and O-H⋯O hydrogen bonds, as well as π-π inter-actions with centroid-centroid distances of 3.514 (3) Å connect the various components into a supra-molecular structure.

Dimethyl 2,6-dimethyl-1,4-dihydro-pyridine-3,5-dicarboxyl-ate.

Project description:In the crystal of the title compound, C(11)H(15)NO(4), the mol-ecules are linked into sheets by N-H?O and C-H?O hydrogen bonds. Within the mol-ecule, the 1,4-dihydro-pyridine ring exhibits a distinctive planar conformation [r.m.s. deviation from the mean plane of 0.009?(3)Å], and the other non-H atoms are almost coplanar [r.m.s. deviation = 0.021?(3)?Å] with the 1,4-dihydro-pyridine ring. The conformation of the latter is governed mainly by two intra-molecular C-H?O non-classical inter-actions.

Dimethyl 2,6-dimethyl-4-phenyl-pyridine-3,5-dicarboxyl-ate.

Project description:In the title compound, C(17)H(17)NO(4), the dihedral angle between the benzene and pyridine rings is 75.51 (4)°. The benzene and pyridine rings are both approximately planar (r.m.s. deviations of 0.0040 and 0.0083 Å, respectively), indicating that the pyridine N atom is not protonated. The crystal structure is stabilized by weak inter-molecular C-H⋯O and C-H⋯N inter-actions.
