A density functional theory and wave function theory investigation on the possibility of carbon-free phosphametallocenes [P3MP3]2-and arsenametallocenes [As3MAs3]2- (M=Ni, Pd, Pt) is presented in this work. Staggered singlet D3d [E3ME3]2- (E=P, As)-the smallest inorganic metallocenes possible to construct-proved to be the global minima of the heptaatomic sys- tems and may be targeted in future experiments. Cyclo-P3- and cyclo-As3- turned out to possess similar aromaticity to cyclo-P5- and cyclo-As5- and may serve as effective ligands to sandwich a wide range of transition metals. The first vertical electron detachment energies of Cs [E3ME3]Li+ monoanions with a staggered [E3ME3]2- sandwich core were predicted to be between 2.7 and 2.9 eV; the extent of stabilization by Li+ suggests that such materials be viable targets for experimental characterization.

“待到山花烂漫时,她在丛中笑。”不知有多少人在梦中神往着这样的场景。  你看,满山锦簇着的野花,色彩斑斓,姹紫嫣红。即使一山的花海颜色不一,仍能神奇地融为一体。每朵花都娇艳欲滴,艳丽逼人,又相辅相成,不可分割。如此胜景,即使不曾亲临其境,仅凭着想象,你也不得不感慨一声:“此景只应天上有,人间难得几回闻!”  我所倾慕的不单是那美景,更是一种品性,一种独属于山花的品性。我特意择了一个清晨,迎着微润的
