N'-(4-Bromo-benzyl-idene)isonicotino-hydrazide.

ABSTRACT: The title compound, C(13)H(10)BrN(3)O, was prepared by the reaction of isonicotinohydrazide and 4-bromo-benzaldehyde. The dihedral angle between the benzene and pyridine rings is 8.60 (12)°. The crystal packing is stabilized by inter-molecular C-H⋯O and N-H⋯O hydogen-bonding inter-actions.

Bis[N'-(3-cyano-benzyl-idene)isonicotino-hydrazide]silver(I) trifluoro-acetate.

Project description:In the title compound, [Ag(C(14)H(10)N(4)O)(2)]CF(3)CO(2), the Ag(I) ion is coordinated by two N atoms of the pyridine rings of two N'-(3-cyano-benzyl-idene)isonicotinohydrazide ligands in a nearly linear geometry. In the crystal structure, a combination of close contacts formed via Ag?N inter-actions [Ag?N = 3.098?(2) and 3.261?(2)?Å] from symmetry-related mol-ecules and inter-molecular N-H?O hydrogen bonds between CF(3)CO(2) (-) anions and the hydrazone groups of two ligands give rise to chains. Furthermore, there are Ag?O inter-actions with a separation of 2.765?(2)?Å between chains. The F atoms of the CF(3)CO(2) (-) anion are disordered over two sites with refined occupancies of 0.593?(5) and 0.407?(5).

Bis[N'-(3-cyano-benzyl-idene)isonicotino-hydrazide-?N]silver(I) trifluoro-methane-sulfonate.

Project description:In the title compound, [Ag(C(14)H(10)N(4)O)(2)]CF(3)SO(3), two N atoms from two independent pyridyl rings of two N'-3-cyano-benzyl-ideneisonicotinohydrazide ligands coordinate to the unique Ag(I) ion, forming a nearly linear coordination geometry. Adjacent silver complexes are primarily linked together by Ag?N inter-actions, with Ag?N separations of 2.877?(2) and 3.314?(2)?Å. On the other hand, one CF(3)SO(3) (-) anion inter-acts with hydrazone groups of two neighbouring ligands via N-H?O hydrogen bonds. These weak inter-molecular inter-actions contribute to the formation of supra-molecular chains. In addition, there are Ag?O inter-actions [2.787?(2)?Å] between Ag and O atoms from adjacent chains.
