The title Schiff base compound, C(15)H(16)N(2)O(2), was prepared by the condensation reaction of equimolar quanti-ties of 3-eth-oxy-salicyl-aldehyde with 2-amino-3-methyl-pyridine in methanol. The dihedral angle between the benzene ring and the pyridine ring is 2.6 (2)° and an intra-molecular O-H⋯N hydrogen bond generates an S(6) ring.

In the title compound, [HgCl(2)(C(6)H(8)N(2))(2)], the two independent Hg(II) cations are each located on a twofold rotation axis and coordinated by two pyridine N atoms from two 2-amino-3-methyl-pyridine ligands and two Cl(-) anions in a distorted tetra-hedral geometry. An intra-molecular N-H⋯Cl hydrogen bond occurs in each independent complex mol-ecule. Inter-molecular N-H⋯Cl hydrogen bonds o...

Two neutral iridium complexes with l-alanine as ancillary ligands, (thp)2Ir (l-alanine) (Ir1) (thp = 2-(thiophen-2-yl)pyridine) and (btp)2Ir (Ir2) (btp 2-(benzo[b]thiophen-2-yl)pyridine) were synthesized investigated. The solid-state structures of the developed Ir1 Ir2 authenticated by single X-ray diffraction. Ir(III) exhibit intense yellow red emission respectively high quantum efficiencies (...

The synthesis, characterization and biological activity of Cu(II) and Ni(II) complexes derived from tridentate Schiff base ligand 3-hydroxy-4-(pyridine-2-yl methylene amino) benzoic acid (HL) was obtained by the condensation of 2-Pyridine carboxaldehyde with 4-amino 3-hydroxy benzoic acid has been described. The complexes were characterized based on elemental analyses, molar conductivity measur...

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...

There are two independent mol-ecules in the asymmetric unit of the title compound, C(10)H(10)BrN(3)O(2), which are linked by N-H⋯O and C-H⋯O hydrogen bonds. The fused ring systems in both mol-ecules are nearly planar with maximum deviations of 0.001 (3) and 0.029 (3) Å. All non-H atoms of the first mol-ecule are approximately co-planar whereas in the second mol-ecule, the ethyl group is almost ...

In the title compound, [CoCl(2)(C(6)H(8)N(2))(2)], the Co(II) ion is four-coordinated by two pyridine N atoms from the 2-amino-3-methyl-pyridine ligands and two chloride ions in a distorted tetra-hedral geometry. A weak intra-molecular N-H⋯Cl inter-action occurs. The crystal packing is stabilized by inter-molecular N-H⋯Cl and C-H⋯Cl hydrogen-bond inter-actions.

The mol-ecule of the title compound, C(10)H(9)N(3)S, is almost planar, with a dihedral angle of 1.38 (4)° between the thio-phene and pyridine rings. In the crystal packing, mol-ecules are linked into layers parallel to the ab plane by inter-molecular N-H⋯N hydrogen bonds and by π⋯π stacking inter-actions involving adjacent pyridine and thio-phene rings with a centroid-centroid distance of 3.537...

The mol-ecule of the title compound, C(10)H(10)N(2)O(2)S, is essentially planar, except for the ethyl group, which is twisted away from the carboxyl plane by -90.5 (3)°. In the crystal structure, mol-ecules are linked into a zigzag sheet propagating along the b axis by inter-molecular N-H⋯O and N-H⋯N hydrogen bonds.
