Vapochemically and mechanochemically reversible polymerization/depolymerization of S–Fe–Cu carbonyl clusters†
Abstract
A reversible vapochemical and mechanochemical solid-state transformation between a dppe-linked SFe3Cu2-based cluster [{(μ3-S)Fe3(CO)9}Cu2(dppe)] (2) and its 1D polymer [{(μ4-S)Fe3(CO)9}Cu2(dppe)(MeCN)2]n (3) was demonstrated, in which polymer 3 exhibited semi-conducting properties with an energy gap of 1.69 eV.
