Synthetic approaches to 2-arylbenzimidazoles: A review

Series of coordination complexes of Ni(II), Cu(II), Zn(II), Cd(II) and Sn(II) metal with 4-amino-5-(pyridyl)-4H-1,2,4-triazole-3-thiol, as a ligand has been successfully prepared in alcoholic medium. The prepared complexes were characterized quantitatively and qualitatively by using: microelemental analysis, FTIR spectroscopy, UV-visible spectroscopy, 1H and 13C NMR, magnetic susceptibility and conductivity measurements. This triazole ligand act as bidentate that coordination to the metal ions through sulphur and amine group. According to the spectral data of the complexes a tetrahedral geometry was suggested for these complexes except Cu (II) complexes which exhibit a square structure.

Dimeric complexes of transition metal based on azole nucleating ligands involving hydrogen bonding interactions

In the title compound, C36H24N2O2, the two naphthyl systems are approximately perpendicular to each other and the two 4-cyano­benz­yloxy rings are almost parallel to each other. There are strong π–π inter­actions [3.835 (3) A] between neighbouring mol­ecules. The face-to-face π–π inter­actions between the benzene rings of neighbouring mol­ecules stabilize the crystal structure to form a one-dimensional chain structure along the a axis.

4,4′-[1,1′-Binaphthalene-2,2′-diyldi(oxymethylene)]benzonitrile

Two new Zn(II) complexes, [Zn(L)2(H2O)2] where L is 1-substituted 5-methyl-1H-[1,2,3]-triazole-4-carboxylic acid, have been synthesized and characterized by elemental analysis, FT–IR, and solid-state fluorescent emission spectroscopy. Structures have been established by single-crystal X-ray diffraction, revealing the discrete nature of the complexes in which Zn centers adopt slightly distorted octahedral geometry. In the complexes, the 1-substituted 5-methyl-1H-[1,2,3]-triazole-4-carboxylic acid is bidentate.

In situ hydrothermal synthesis and structural characterization of two novel CdII–tetrazole coordination polymers

Two new one-dimensional chain coordination polymers were synthesized by reaction of 5-methyl-1-phenyl-1H-1,2,3-triazole-4-carboxylic acid (Hmptca) and CuCl2, or NiCl2, respectively, under hydrothermal conditions Both have non-centrosymmetric polar packing arrangements (polar point group Cs), which result in dielectric properties

Synthesis, Structural, and Electrical Characterization of two Novel Coordination Polymers based on a [1,2,3]-Triazole Carboxylic Acid Derivative Ligand

The title compound, C37H26N2O2, was synthesized from 1,1′-methyl­enedinaphthalen-2-ol and 3-(bromo­methyl)­benzo­nitrile. The two naphthyl systems are almost perpendicular to each other [dihedral angle 83.3 (9)°] and the two cyano­benz­yloxy rings approximately parallel to each other [dihedral angle 15.5 (2)°].
