A three-dimensional network of two-electron-transferred [Ru2]2TCNQ exhibiting anomalous conductance due to charge fluctuations

Abstract

A new D₂A-type charge-transfer three-dimensional network with a charge distribution of [{Ru₂}^δ+–(BTDA-TCNQ^2δ−)–{Ru₂}^δ+] where δ ≈ 1, which exhibits a sudden decrease in electronic resistance, formed from the assembly of a paddlewheel diruthenium(II, II) complex ([Ru₂]) as a donor (D) and bis(1,2,5-thiadiazolo)tetracyanoquinodimethane (BTDA-TCNQ) as an acceptor (A).
