In the title complex, [Cd(C₁₃H₈N₅)₂(C₂H₅OH)₂], the Cd^II cation is located on an inversion center and coordinated by two deprotonated 2-(1H-benzotriazol-1-yl)-1H-benzimidazol-1-ide (L) ligands and two ethanol molecules in a distorted N₄O₂ octahedral geometry. In the L ligand, the dihedral angle between benzoimidazole and benzotriazole ring systems is 10.8 (3)°. In the crystal, the complex molecules are connected by O-HN hydrogen bonds; intermolecular [pi] - [pi] stacking is also observed [centroid-centroid distances of 3.668 (5) Å between triazole and benzene rings and 3.780 (5) Å between imidazole rings].
