Gerüstumlagerung pentagonal pyramidaler Käfige: Tandem-Isomerisierung

Abstract The six vertex clusters (RP)Fe 3 (CO) 9 (R′CCR″) readily isomerize into each other. On the basis of EHT model calculations on the isolobal system B 6 H 6 4− a “tandem process” is proposed as the isomerization pathway, which involves a distorted trigonal prismatic intermediate.
