Zusammenfassung
The reaction of (LCrCrL)-Cr-5 (L = N2C25H29, 1) with the phosphaalkynes R-C P (R = tBu, Me, Ad) yields the neutral dimerisation compounds [L2Cr2(mu,eta(1): eta(1): eta(2): eta(2)-P2C2R2)] (R = tBu (2), Me (3)) and the tetrahedrane complex [L2Cr2(mu,eta(2): eta(2)-P = CAd)] (4). The 1,3-diphosphete ligands in complexes 2 and 3 are the first to possess this structural feature spanned over a ...
