Chalcogen abstraction from dithiadiazolyl and diselenadiazolyl platinum complexes: crystal structure of a novel metalla-heterocycle
Abstract
The open-shell complexes, (PhCNEEN)Pt(dppe) (E = S or Se) decompose via a chalcogen abstraction process coupled with N-protonation to yield the novel 10π metalla-heterocyclic cations {[PhCN(H)N(H)E]Pt(dppe)}+: the selenium complex is characterised by X-ray crystallography as its chloride salt.
