Linear Multiselenium Interactions in Dicationic Oligomers of 1,5‐(Diselena)canes: Behavior of Se mc σ( m c c‐ n e e) (6≤ m c ≤16) Elucidated with QTAIM Dual Functional Analysis

Invited for this month's cover picture is the group of Dr. Satoko Hayashi at Faculty of Systems Engineering and Chemistry at Wakayama University. The cover picture shows the linear Se(16) σ(16c–30e) interactions, illustrated by the molecular graph type on the optimized structure of the dicationic octamer of 1,5‐(diselena)cane. HOMO‐1 of ψ(462) is drawn on the structure, which is located predominantly on the Se atoms. The optimized structure is stable, due to the nice engagement between the (CH(2))(3) moieties. The contour maps of ρ(r) are also drawn on the molecular C (s) planes of the dicationic dimer and trimer to demonstrate clearly the existence of the interactions between Se atoms.
