Abstract: | Abstract Two new complexes, [Ag(L)2](NO3) · (H2O) (1) and [Co(L)2Cl2] (2) [L = 1-(imidazol-1-yl-methyl)-benzotriazole], have been synthesized and structurally characterized by X-ray diffraction techniques. In complex (1), the Ag(I) atom adopts a linear coordination geometry involving the imidazole nitrogens of two ligands. The [Ag(L)2] units are developed into a three-dimensional structure by intermolecular hydrogen bonds, π–π interactions, and Ag···O interactions. In complex (2), the Co(II) atom is in a distorted tetrahedral environment with two imidazole nitrogens and two chloride ligands. The [Co(L)2Cl2] units are assembled into a three-dimensional structure by intermolecular hydrogen bonds and π–π interactions. The bioactivities of both complexes have been studied, and the results indicate that complex (1) exhibits excellent radical-scavenging (RS) and fungicidal (FG) activities while complex (2) only has weak fungicidal activity.

The molecules of complexes (1) and (2) are extended to 2-D and 3-D structures by the non-coordinated bonds. The ligand and complex (1) exhibit excellent radical-scavenging and fungicidal activities.
