Pyridine-4-carbaldehyde-fumaric acid (2/1).

ABSTRACT: In the title co-crystal, 2C6H5NO·C4H4O4, two crystallographically different hydrogen-bonded trimers are formed, one in which the components occupy general positions, and one generated by an inversion centre. This results in the uncommon situation of Z = 3 for a triclinic crystal. In the formula units, mol-ecules are linked by O-H?N hydrogen bonds.

In the title co-crystal, 2C6H5NO·C4H4O4, two crystallographically different hydrogen-bonded trimers are formed, one in which the components occupy general positions, and one generated by an inversion centre. This results in the uncommon situation of Z = 3 for a triclinic crystal. In the formula units, mol-ecules are linked by O-H⋯N hydrogen bonds. ...[more]

Project description:In the title compound, [Cu(C(6)H(5)N(2)O)Cl(C(6)H(6)N(2)O)], the Cu atom is coordinated by one neutral and one deprotonated pyridine-2-carboxaldehyde oxime (pco) ligand, resulting in the formation of two five-membered CuN(2)C(2) rings. Together with the additional coordinating chloride anion, the coordination polyhedron of copper is best described as a distorted square-pyramid, the distortion parameter being 0.288. The two organic ligands are linked by an intramolecular O-H?O hydrogen bond.

Pyridine-4-carbaldehyde 4-phenylsemicarbazone.

Project description:In the title compound, C(13)H(12)N(4)O, the semicarbazone fragment links a benzene and a pyridine ring in the structure. The crystal packing is stabilized by strong inter-molecular N-H?O hydrogen bonds, which connect two mol-ecules to form a synthon unit, and by N-H?N hydrogen bonds and weak C-H?? inter-actions. The mol-ecular conformation is stabil-ized by intra-molecular N-H?N and C-H?O inter-actions.

Project description:The crystal structure of the title Fe(II) complex, [Fe(NCS)(2)(C(7)H(8)N(4)S)(2)(CH(3)CH(2)OH)(2)]·2C(7)H(8)N(4)S, based on the Schiff base ligand pyridine-3-carbaldehyde thio-semicarbazone (pct), results from the cocrystallization of an Fe(II) coordination compound together with two of the pct ligands.

The slightly distorted octa-hedral coordination is completed by two O atoms from ethanol mol-ecules. The crystal packing is accomplished inter-molecular N-H?S hydrogen bonds.

Gallic acid pyridine monosolvate.

Project description:IN THE TITLE COMPOUND (SYSTENATIC NAME: 3,4,5-trihy-droxy-benzoic acid pyridine monosolvate), C(5)H(5)N·C(7)H(6)O(5), the gallic acid mol-ecule is essentially planar (r.m.s deviation = 0.0766?Å for non-H atoms) and is linked to the pyridine mol-ecule by an O-H?N hydrogen bond. An intra-molecular O-H?O hydrogen bond occurs in the gallic acid mol-ecule. The gallic acid and pyridine mean planes make a dihedral angle 12.6?(3)°. Inter-molecular O-H?O and O-H?N hydrogen bonding involving the hy-droxy and carboxyl groups and the pyridine mol-ecule, and ?-? inter-actions between inversion-related pyridines [centroid-centroid distance = 3.459?(6)?Å] and between pyridine and benzene rings [centroid-centroid distance = 3.548?(6)?Å], lead to a three-dimensional network in the crystal.
