Redetermined structure of 4,4'-bi-pyridine-1,4-phenyl-enedi-acetic acid (1/1) co-crystal.

ABSTRACT: The asymmetric unit of the title 1:1 co-crystal, C10H8N2·C10H10O4, consists of one half-mol-ecule each of 4,4'-bi-pyridine and 1,4-phenyl-enedi-acetic acid: the complete mol-ecules are generated by crystallographic inversion centres. The dihedral angle between the -CO2H group and the benzene ring in the diacid is 73.02?(7)°. In the crystal, the components are linked by O-H?N hydrogen bonds, generating [1-2-1] chains of alternating amine and carb-oxy-lic acid mol-ecules. The chains are cross-linked by C-H?O inter-actions. This structure was previously incorrectly described as a (C10H10N2)(2+)·(C10H8O4)(2-) mol-ecular salt [Jia et al. (2009 ?). Acta Cryst. E65, o2490-o2490].

Crystal structure of 4,4'-dimeth-oxy-2,2'-bi-pyridine.

Project description:In the title compound, C12H12N2O2, the dihedral angle between the planes of the two pyridine rings is 5.8 (1)°. Neighbouring mol-ecules are linked via C(Me)-H⋯N inter-actions, generating a two-dimensional sheet structure; C-H⋯π inter-actions further link the mol-ecules into a three-dimensional network. An overlapped arrangement of parallel pyridine rings in neighbouring mol-ecules [centroid-to-centroid distance = 3.6655 (15) Å] is observed in the crystal structure.

Partial charge transfer in the salt co-crystal of l-ascorbic acid and 4,4'-bi-pyridine.

Project description:In the title 1:2 co-crystal, C10H9N2 +·(C6H7.75O6·C6H7.25O6)-, l-ascorbic acid (LAA) and 4,4'-bi-pyridine (BPy) co-crystallize in the chiral space group P21 with two mol-ecules of LAA, and one mol-ecule of bpy in the asymmetric unit. The structure was modeled in two parts due to possible proton transfer from LAA to the corresponding side of the bpy mol-ecule having an occupancy of approximately 0.25 and part 2 with an occupancy of approximately 0.75. In this structure, LAA forms hydrogen bonds with neighboring LAA mol-ecules, forming extended sheets of LAA mol-ecules which are bridged by bpy mol-ecules. A comparison to a related and previously published co-crystal of LAA and 3-bromo-4-pyridone is presented.

Synthesis and crystal structure of a new coordination polymer based on lanthanum and 1,4-phenyl-enedi-acetate ligands.

Project description:Reaction in gel between the sodium salt of 1,4-phenyl-enedi-acetic acid (Na2C10O4H8-Na2 p-pda) and lanthanum chloride yields single crystals of the three-dimensional coordination polymer poly[[tetra-aqua-tris-(?-1,4-phenyl-enedi-acetato)-dilanthanum(III)] octa-hydrate], {[La2(C10H8O4)3(H2O)4]·8H2O}?. The LaIII coordination polyhedron can be described as a slightly distorted monocapped square anti-prism. One of the two p-pda2- ligands is bound to four LaIII ions and the other to two LaIII ions. Each LaIII atom is coordinated by five ligands, thereby generating a metal-organic framework with potential porosity properties.

Crystal structures of tetra-methyl-ammonium (2,2'-bi-pyridine)-tetra-cyanidoferrate(III) trihydrate and poly[[(2,2'-bi-pyridine-?(2) N,N')di-?2-cyanido-dicyanido(?-ethyl-enedi-amine)(ethyl-enedi-amine-?(2) N,N')-cadmium(II)iron(II)] monohydrate].

Project description:The crystal structures of the building block tetra-methyl-ammonium (2,2'-bi-pyridine-?(2) N,N')tetra-cyanidoferrate(III) trihydrate, [N(CH3)4][Fe(CN)4(C10H8N2)]·3H2O, (I), and a new two-dimensional cyanide-bridged bimetallic coordination polymer, poly[[(2,2'-bi-pyridine-?(2) N,N')di-?2-cyanido-dicyanido(?-ethyl-enedi-amine-?(2) N:N')(ethyl-enedi-amine-?(2) N,N')cadmium(II)iron(II)] monohydrate], [CdFe(CN)4(C10H8N2)(C2H8N2)2]·H2O, (II), are reported. In the crystal of (I), pairs of [Fe(2,2'-bipy)(CN)4](-) units (2,2'-bipy is 2,2'-bi-pyri-dine) are linked together through ?-? stacking between the pyridyl rings of the 2,2'-bipy ligands to form a graphite-like structure parallel to the ab plane. The three independent water mol-ecules are hydrogen-bonded alternately with each other, forming a ladder chain structure with R 4 (4)(8) and R 6 (6)(12) graph-set ring motifs, while the disordered [N(CH3)4](+) cations lie above and below the water chains, and the packing is stabilized by weak C-H?O hydrogen bonds. The water chains are further linked with adjacent sheets into a three-dimensional network via O-H?O hydrogen bonds involving the lattice water mol-ecules and the N atoms of terminal cyanide groups of the [Fe(2,2'-bipy)(CN)4](-) building blocks, forming an R 4 (4)(12) ring motif. Compound (II) features a two-dimensional {[Fe(2,2'-bipy)(CN)4Cd(en)2]} n layer structure (en is ethyl-enedi-amine) extending parallel to (010) and constructed from {[Fe(2,2'-bipy)(CN)4Cd(en)]} n chains inter-linked by bridging en ligands at the Cd atoms. Classical O-H?N and N-H?O hydrogen bonds involving the lattice water mol-ecule and N atoms of terminal cyanide groups and the N-H groups of the en ligands are observed within the layers. The layers are further connected via ?-? stacking inter-actions between adjacent pyridine rings of the 2,2'-bipy ligands, completing a three-dimensional supra-molecular structure.

Project description:The title compound, [CuCl2(C12H12N2)] n , was obtained via a DMSO-mediated dehydration of Cu(4,4'-dimethyl-2,2'-bi-pyridine)-copper(II)·0.25H2O. The central Cu(II) atom is coordinated in a distorted trigonal-bipyramidal geometry by two N atoms of a chelating 4,4'-dimethyl-2,2'-bi-pyridine ligand [average Cu-N = 2.03?(3)?Å] and three Cl atoms, one terminal with a short Cu-Cl bond of 2.2506?(10)?Å, and two symmetry-equivalent and bridging bonds. The bridging Cl atom links the Cu(II) ions into chains parallel to [001] via one medium and one long Cu-Cl bond [2.3320?(10) and 2.5623?(9)?Å]. The structure displays both inter- and intra-molecular C-H?Cl hydrogen bonding.

In the crystal, O-H?O hydrogen bonds link the organic mol-ecules and water mol-ecules, forming zigzag chains the c axis. An intra-molecular O-H?O hydrogen bond is also observed.
