Pyridine-2,3-diamine
The mol-ecule of the title pyridine derivative, C(5)H(7)N(3), shows approximately non-crystallographic C(s) symmetry. Intra-cyclic angles cover the range 117.50 (14)-123.03 (15)°. In the crystal, N-H⋯N hydrogen bonds connect mol-ecules into a three-dimensional network. The closest inter-centroid distance between two π-systems occurs with the c-axis repeat at 3.9064 (12) Å.
متن کاملPyridine-2,5-diamine
In the title mol-ecule, C5H7N3, intra-cyclic angles cover the range 117.15 (10)-124.03 (11)°. The N atoms of the amino groups have trigonal-pyramidal configurations deviating slightly from the pyridine plane by 0.106 (2) and -0.042 (2) Å. In the crystal, the pyridine N atom serves as an acceptor of an N-H⋯N hydrogen bond which links two mol-ecules into a centrosymmetric dimer. Inter-molecular N...
متن کامل5-Bromo-N 3-[(E)-(6-bromopyridin-2-yl)methylidene]pyridine-3,4-diamine
The title compound, C(11)H(8)Br(2)N(4), is a Schiff base obtained from 6-bromo-picolinaldehyde and 5-bromo-pyridine-3,4-diamine. The mol-ecule has an E configuration about the C=N bond and the dihedral angle between the two pyridine rings is 14.02 (1)°. The observed conformation is stabilised by an intramolecular N-H⋯N hydrogen bond. In the crystal, mol-ecules are stacked along the b axis and a...
متن کاملNovel Neodymium(III) Membrane Sensor based on N-(2-Furylmethylene)pyridine-2,6-diamine
Através de nossos estudos, encontramos que N-(2-furilmetileno) piridina-2,6-diamina (FPD) pode ser usado como um excelente ionóforo na construção de um novo sensor baseado em membrana de poli(vinil cloreto) (PVC). Uma composição para a membrana, de 33% de PVC, 59% de nitrobenzeno (NB), 6% de FPD e 2% de borato de potássio tetrakis (p-clorofenil) (KTpClPB), levou a ótimos resultados. A seletivid...
