Transformation of nortricyclane type cage compounds P4S3, P4Se3 and As4S3 by [Cp′′2Zr(CO)2]†
Abstract
The complex [Cp′′2Zr(CO)2] (Cp′′ = C5H3tBu2) was used to transform the nortricyclane type cage compounds E4Q3 (E = P, Q = S, Se; E = As, Q = S) resulting in unprecedented complexes [(Cp′′2Zr)2(μ,η1:1:1:1-E2Q4)] possessing bridging ligands that represent the anions of the so far unknown tetrachalcogenohypodiphosphorous acid (HQ)2PP(QH)2 and tetrathiohypodiarsenous acid (HS)2AsAs(SH)2, respectively.
