Theoretical study of bicyclo[2.2.0]hexaplumbane. A more flexible and less strained Pb skeleton compared with C, Si, Ge, and Sn skeletons
Abstract
Ab initio calculations predict that bicyclo[2.2.0]hexaplumbane is less strained than its lighter analogues and prefers C2 to C2v symmetry, but the energy difference between C2 and C2v is remarkably small despite the considerable geometrical differences.
