Abstract
A series of lithiated and sodiated α, α′-stabilized carbanions, [RSO 2 CHCN]− and [(RO) 2 P(O)CHCN]− have been characterized in the solid-state and found to adopt related structures. A common structural theme is the “head-to-tail” bonding of the ligands to form ring dimers, polymeric chains, or two-dimensional networks.
