[Cyanil](2)(2-) dimers possess long, two-electron ten-center (2e(-)/10c) multicenter bonding.
A long, two-electron ten-center (2e(-)/10c) [8 carbon plus 2 oxygen] bond in diamagnetic dimers of radical-anion tetracyano-1,4-benzoquinoneide (cyanil, [Q] (-)), [Q](2)(2-), is described by B3LYP and CASSCF(2,2)/MCQDPT calculations.
