Charge-transfer spectra of organometallic complexes - VII. Electron-donor-acceptor complexation of trialkyltinisothiocyanates with iodine and tetracyanoethylene
An ultraviolet-visible study of the charge-transfer interaction between R3SnNCS (R = Me, Et, iPr and nBu) and iodine, respectively, tetracyanoethylene has revealed that the HOMO with dominant lone pair character located on S is the preferred donor site in
