Abstract

An ionic molecular crystal of (1′,1′′′-dineopentylbiferrocene)(F1TCNQ)3 exhibits a first-order phase transition from a monovalent state (D+A3−) to a divalent state (D2+A32−) at around 120 K. The transition was successfully controlled by modulation of the redox potentials using FnTCNQ (n = 0–2) and by chemical-pressure effects.
