The title compound [systematic name: 4-(di-methyl-amino)-pyridine-4-meth-oxy-phenyl-borane (1/1)], C14H19BN2O, contains two independent mol-ecules in the asymmetric unit. Both molecules exhibit coplanar, mostly sp2-hybridized meth-oxy and di-methyl-amino substituents on their respective aromatic rings, consistent with π-donation into the aromatic systems. The B-H groups exhibit an intra-molecul...

The Pd(II) ion in the title complex, [PdCl(2)(C(14)H(10)N(4))], is four-coordinated in a distorted square-planar environment defined by two N atoms of a chelating 2,3-di-2-pyridyl-pyrazine (dpp) ligand and two chloride anions. The pyridine ring coordinated to the Pd atom is inclined slightly to its carrier pyrazine ring [dihedral angle = 14.4 (3)°], whereas the uncoordinated pyridine ring is in...

A series of dimetallic and monometallic Cp*Ir(III) complexes bearing naphthalene-diimide-decorated N-heterocyclic carbene/pyridine [NDI-(NHC-pyridine)] ligands were prepared characterized. The show a C,C-chelating coordination the NHC-pyridine ligand, with pyridine ring ligand bound to metal via cyclometallation rather than by its nitrogen atom, although atom could be achieved subjecting one re...

a new metal-organic compound, [fe(pydc)(dmso)(h2o)cl], (where pydc is pyridine-2, 6-dicarboxylate and dmso is dimethyl sulfoxide), has been synthesized and characterized by singlecrystal x-ray diffraction, tga/dta, ir and raman spectroscopy. green-yellow crystals,crystallized in the monoclinic system, space group p21/n, a = 7.2461(4) å, b = 10.3018(4) å, c =17.7667(10) å, α = 90°, β = 90.014°(5...

The title compound, C(29)H(29)NO(3), the nearly planar nine-membered indanedione ring [maximum deviation = 0.027 (2) Å] is located approximately parallel to its carrier pyridine ring [maximum deviation = 0.021 (2) Å] with a dihedral angle of 1.8 (1)° between the planes. However, because of steric hindrance, the benzene ring [maximum deviation = 0.006 (2) Å] is not parallel to the pyridine ring ...

Quinolinic acid (pyridine-cr , /3-dicarboxylic acid) has been isolated from rat urine after administration of tryptophan to rats (1). It has been suggested that quinolinic acid is formed via 3-hydroxyanthranilic acid by oxidative cleavage of the benzene ring in the 3-4 position, followed by closure incorporating the amino nitrogen in a pyridine ring (1). In this paper are reported the results o...

In the title compound, C(12)H(11)FN(4)O(2), the pyridine ring is connected to a benzene ring by a -CH(2)-NH(2)- chain. The nitro group is twisted out of the pyridine ring plane [torsion angle O-N-C-C = 10.41 (10)°]. An intramolecular N-H⋯O hydrogen bond occurs. The fluoro-benzene ring is disordered over two positions [occupancy ratio = 0.59 (3):0.41 (3)]. Inter-molecular N-H⋯O and N-H⋯N hydroge...

The cation of the title compound, C(36)H(34)N(6)O(2) (2+)·2PF(6) (-), lies across a crystallographic inversion centre. The imidazole and pyridine rings form dihedral angles of 82.28 (5)° and 11.87 (7)°, respectively, with the anthracene ring system. The crystal packing is stabilized by π-π inter-actions between the pyridine ring and the central ring of anthracene, with a ring centroid-centroid ...

The title compound, C23H21N3, comprises a 2-amino-3-cyano-pyridine ring fused with a cyclo-pentane ring. The later adopts an envelope conformation with the central methyl-ene C atom as the flap. The benzyl and and p-tolyl rings are inclined to one another by 56.18 (15)°, and to the pyridine ring by 81.87 (14) and 47.60 (11)°, respectively. In the crystal, mol-ecules are linked by pairs of N-H⋯N...
