2-Benzoyl-pyridine semicarbazone.

ABSTRACT: The title compound, C(13)H(12)N(4)O, crystallizes with two independent mol-ecules in the asymmetric unit. The compound crystallizes as the ZE isomer, where Z and E refer to the configuration around the C=N and N-C bonds, respectively, with an N-H?N(py) (py is pyridine) intra-molecular hydrogen bond. The dihedral angles between the least-squares planes through the semicarbazone group and the pyridyl ring are 22.70?(9) and 27.26?(9)° for the two mol-ecules. There are intermolecular N-H?O hydrogen bonds.

Crystal structure of 4-formyl-pyridine semicarbazone hemihydrate.

Project description:The mol-ecule of the title compound C7H8N4O·0.5H2O, alternatively called (E)-1-(pyridin-4-yl-methyl-ene)semi-carb-azide hemihydrate, is in the E conformation and is almost planar; the r.m.s. deviation of the positions of the atoms of the pyridine ring from the best-fit plane is 0.0039 Å. The C, N and O atoms of the rest of the mol-ecule sits close on this plane with a largest deviation of 0.115 (4) Å for the O atom of the semicarbazone moiety. There is an intra-molecular N-H⋯N hydrogen bond. In the crystal, mol-ecules are linked into an infinite three-dimensional network by classical N-H⋯Os (s = semicarbazone) and Ow-H⋯N (w = water) hydrogen bonds.

Benzoyl-methyl pyridine-4-carboxyl-ate.

Project description:In the crystal structure of the title compound, C(14)H(11)NO(3), isolated from the reaction of 2-bromo-1-phenyl-ethanone and pyridine-4-carboxylic acid using triethyl-amine as a base to deprotonate the organic acid, the mol-ecular packing is stabilized by C-H?? inter-actions involving the phenyl and pyridine rings. The C-C-O-C torsion angle for the linkage between the two carbonyl groups is -80.8?(2)°, and the planes of the phenyl and pyridyl rings form a dihedral angle of 65.8?(1)°.

Bis(ethanol-?O)bis-(pyridine-3-carb-aldehyde-?N thio-semicarbazone)bis-(thio-cyanato-?N)iron(II)-pyridine-3-carbaldehyde thio-semicarbazone (1/2).

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 complex unit is mononuclear, with the central Fe(II) ion located on a crystallographic centre of inversion and coordinated by four N atoms from two pct ligands and two thio-cyanate anions. 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.

catena-Poly[[bis-(3-benzoyl-pyridine-κN)zinc(II)]-di-μ-dicyanamido-κN:N].

Project description:The title compound, [Zn(C(2)N(3))(2)(C(12)H(9)NO)(2)](n), is a polymeric zinc(II) complex with the metal ion located on an inversion centre. The Zn(II) ion is six-coordinated by two N atoms of two 3-benzoyl-pyridine ligands and four N atoms from four dicyanamide ligands, forming a slightly distorted octa-hedral configuration. In the crystal structure, neighboring Zn atoms are linked together by double dicyanamide bridges to form a polymeric zinc(II) complex.

Bis(N'-benzoyl-pyridine-4-carbohydrazide)(1,10-phenanthroline)copper(II) dinitrate.

Project description:In the title complex, [Cu(C(13)H(11)N(3)O(2))(2)(C(12)H(8)N(2))](NO(3))(2), the Cu(II )atom (site symmetry 2) is coordinated by four N atoms from one 1,10-phenanthroline and two hydrazine ligands, respectively. The hydrazine ligands coordinate to the Cu(II)atom by a pyridine N atom. These four atoms form a slightly distorted square-planar N(4) donor set. In the packing, two additional Cu?O inter-actions occur [Cu?O = 2.462?(2)?Å], resulting in a typical Jahn-Teller-distorted octahedral environment around the Cu atom. N-H?O hydrogen bonds result in a three-dimensional network. The O atoms of the anion are disordered over two positions in a 0.68?(2):0.32?(2) ratio.

Project description:In the title compound, C(27)H(25)NO(4), the tetra-hydro-pyridine ring adopts a half-chair conformation.

The mol-ecular conformation is stabilized by an intra-molecular O-H⋯O hydrogen bond, generating an S(6) motif.

[?-4-Benzoyl-1-(1-oxido-2-naphthyl-carbon-yl)thio-semicarbazidato(4-)]bis-[pyridine-copper(II)].

Project description:In the title dinuclear complex, [Cu(2)(C(19)H(11)N(3)O(3)S)(C(5)H(5)N)(2)], the two Cu(II) centers have different coordination environments, viz. N(2)OS and N(2)O(2), each exhibiting a distorted square-planar geometry. ?-? inter-actions between the aromatic rings of neighbouring complexes [centroid-centroid distance = 3.856?(5)?Å] link pairs of mol-ecules into centrosymmetric dimers, which are further packed into stacks along the b axis with relatively short Cu?Cu separations of 3.482?(1)?Å. Weak inter-molecular C-H?N hydrogen bonds help to consolidate the crystal packing.

Benzaldehyde thio-semicarbazone.

Project description:The title compound, C(8)H(9)N(3)S, contains two mol-ecules in the asymmetric unit. One mol-ecule is close to being planar (r.m.s. deviation from the mean plane = 0.06 Å for the non-H atoms), while the other exhibits a dihedral angle of 21.7 (1)° between the benzene ring and the mean plane of the thio-semicarbazone unit. Inter-molecular N-H⋯S hydrogen bonds link the mol-ecules into layers parallel to the (010) plane.
