Abstract
Die kürzeste I-I-Bindung in der R3PI2-Chemie ist entdeckt! Durch Verwendung geeigneter Substituenten am elektronenziehenden o-Carboranyl-Fragment kann die I-I-Bindung kontinuierlich bis zur Rekordlänge verkürzt werden. Die Verbindung (1-PiPr2-2-Me-1,2-C2B10H10)⋅I2 wird unter bindungstheoretischen Gesichtspunkten diskutiert und kann als molekularer Charge-Transfer-Komplex aufgefasst werden, dessen Struktur an ein Steuerrad mit Spake erinnert (siehe Bild).

Crystal data for 2: Formula C9H27B10I2P, Mr=528.18, crystal size: 0.36×0.34×0.30 mm, monoclinic, space group P21/a (No. 14), a=14.087(4), b=10.358(2), c=15.230(3) Å, β=110.33(2)°, V=2083.9(8) Å3, Z=4, ρcalcd=1.684 g cm−3, μ=3.082 mm−1, F(000)=1008, reflections collected 3835, unique 3673 [Rint=0.0187]. An empirical absorption correction with ψ-scan data was applied. The structure was solved using SIR92 and was refined against |F 2| using program SHELXL-97 (230 parameters). R indices were (all data): R1=0.0524, wR2=0.0727.
