Abstract

Anisotropic ESR spectra (THF, frozen glass, 77 K) of PhCN~2~Se~2~^˙^ provide valuable information about the electronic structure of the diselenadiazolyl radical. Reaction of PhCN~2~Se~2~^˙^ with Pt(PPh~3~)~3~ in CH~2~Cl~2~ yielded the first diselenadiazolyl–metal complex, Pt[PhCN~2~Se~2~][PPh~3~]~2~. The electronic structures of both compounds are described in comparison with their sulphur analogues and the isoelectronic SN~2~E~2~^+˙^ radicals (E = S, Se).
