Summary
Dimeric diethyldithiocarbamatethallium(I) [Et 2NCS2Tl]2 shows a red emission at λmax=608 nm which undergoes a huge Stokes shift with regard to the excitation maximum at λ=246 nm. It is suggested that the emission originates from a sp excited state which is characterized by strong metal-metal bonding.
Zusammenfassung
Dimeres Thallium(I)diethyldithiocarbamat [Et 2NCS2Tl]2 zeigt eine rote Emission mit λmax=608 nm und eine große Stokes'sche Verschiebung im Bezug auf das Anregungsmaximum von λ=246 nm. Die Emission wird einem sp angeregten Zustand zugeordnet, der durch eine starke Metall-Metall Wechselwirkung charakterisiert ist.
