R. Benedix et M. Hofbauer, THEORETICAL AND SPECTROSCOPIC INVESTIGATIONS OF METAL-ORGANIC ION-PAIRS WITH DITHIOLENE OR DITHIOOXALATE DONOR COMPLEXES AND VIOLOGENS, Journal of information recording, 23(1-2), 1996, pp. 85-87
Bipyridinium and phenanthrolinium accepters (A(2+)) Of different reduc
tion potentials and (dithiooxalato) metalates form ion-pair charge-tra
nsfer complexes of the general formula {A[M(dto)(2)]}, where M=Ni, Pd,
Pt, Cu, Zn, and dto = 1,2-dithiooxalate. Compared with analogous ion
pairs consisting of a dithiolene donor component the hypsochromic shif
t of the ion-pair charge-transfer (IPCT) band, which is a characterist
ic feature of the systems is discussed. The particular orbital structu
re of the highest occupied MO influences significantly the electrochem
ical and photochemical properties of both groups of metal-organic ion
pairs.
