Theoretical prediction of stable structures of lithiosilicon species based on planar double, triple, and quadruple silicon rings
Possible planar double, triple, and quadruple lithiosilicon ring structures have been theoretically predicted at the B3LYP/6-311+G (2d, p) level. The structures containing planar double silicon ring as well as triple and quadruple ring could be stable at this level. Meanwhile, it was also demonstrated that Li stabilization was still effective when extending to planar polycyclic silicon rings. (C) 2010 Elsevier B.V. All rights reserved.
