Abstract:
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-benzimid-azol-1-ide (L) ligands and two ethanol mol-ecules in a distorted N4O2 octa-hedral geometry. In the L ligand, the dihedral angle between benzoimidazole and benzotriazole ring systems is 10.8 (3)°. In the crystal, the complex mol-ecules are connected by O-H⋯N hydrogen bonds; inter-molecular π-π 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].

Structure of Conjugated Dienes
Conjugated dienes are compounds characterized by the presence of alternating double and single bonds. In a conjugated system like 1,3-butadiene, the unhybridized 2p orbital on each carbon overlaps continuously, allowing the π electrons to be delocalized across the entire molecule. In contrast, this type of overlap does not occur in cumulated and isolated dienes, such as 2,3-pentadiene and 1,4-pentadiene, respectively. Instead, the π electrons remain localized between the double...
