Abstract

original image

The alkali metal compounds MR (R = C(SiMe3)3, M = Rb, Cs), which are extremely air- and moisture-sensitive, can be synthesized from RH and MMe. Crystals of RbR consist of linear chains of Rb+ ions and distorted planar R- ions, whereas those of CsR contain isolated ion pairs surrounded by lattice C6H6 solvent molecules (shown on the right).
