| Abstract: | A new ligand, 3-methyl-4-(p-bromophenyl)-5-(2-pyridyl)-1,2,4-triazole (L) and its complexes, trans-CuL2(ClO4)2] (1) and cis-CoL2(H2O)2](ClO4)2·H2O·CH3OH (2), have been synthesized and characterized by UV, IR, electrospray ionization mass spectrum, elemental analyses, and single-crystal
X-ray diffraction methods. In the structure, two L ligands are stabilized by intermolecular π···π interactions between the triazole rings. In the complexes, each L ligand adopts a chelating bidentate mode through N atom of pyridyl group and one N atom of the triazole. Both complexes have
a similar distorted octahedral MN4O2] core (M = Cu2+ and Co2+) with two ClO4
− ions in the trans position in 1 but two H2O molecules in the cis arrangement in 2. |
