title: Transformation of nortricyclane type cage compounds P4S3, P4Se3and As4S3by [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)2and tetrathiohypodiarsenous acid (HS)2AsAs(SH)2, respectively.
