Hofbauer, Matthias published the artcileIon-pair charge-transfer complexes of a dithiooxalate zinc donor component with viologens. Synthesis, structural and electronic characterization, Related Products of pyridine-derivatives, the main research area is zincate dithiolato bipyridinium phenanthrolinium pyridylketone preparation; charge transfer zincate dithiolato viologen derivative; electrochem zincate dithiolato viologen derivative; crystal structure zincate dithiolato viologen derivative.
Bipyridinium and phenanthrolinium acceptors of different reduction potentials form with Zn 1,2-dithiooxalates (dto) ion-pair charge-transfer complexes {A2+[Zn(dto)2]2-}. The contact ion pairs exhibit absorptions in the range 390-490 nm which can be attributed to the ion-pair charge-transfer (IPCT) type. On the base of spectroscopic, electrochem. and quantum-chem. studies the relation between optical and thermal electron transfer within the ion pair applying the Hush theory is discussed. The mean reorganization energy of 12 complexes is 180 kJ mol-1 and exceeds the values found for the dithiolene systems. Due to the diminished donor ability of the dithiooxalate unit, a hypsochromic shift of the position of the IPCT band, compared with the metal dithiolenes, results. The extent of electron delocalization from [Zn(dto)2]2- to PQ2+, as described by the parameter α2, is calculated as 4.1 × 10-6. X-ray analyses of BQ[Zn(dto)2] and DP[Zn(dto)2] reveal that the solid-state structure is largely determined by the geometry of the acceptor component.
