Toward (car)borane-based molecular magnets
In a previous work, we reported the electronic structure of dimer diradicals composed of two S = ½ closo-carborane CB<inf>11</inf>H<inf>12</inf>· structural units (Theor. Chem. Acc. (2013) 132: 1329). That work has been extended here in order to describe a linear dimer, a lin...
