摘要：

The triple-decker chromium complexes [(eta(5)-C(5)Me(5))Cr(mu(2):eta(5)-P-5)Cr(eta(5)C(5)Me(5))](+) [A]-(A = PF6, SbF6) can be prepared in high yield by oxidation of [(eta(5)-C(5)Me(5))Cr(mu(2):eta(5)-P-5)Cr(eta(5)-C(5)Me(5))] With either [Fe(eta(5)-C5H5)(2)](+)[A](-) (A=PF(6,), SbF6); the single crystal X-ray structure determination for [(eta(5)-C(5)Me(5))Cr(mu(2):eta(5))-P-5)Cr(eta(5)-C(5)Me(5))](+)[SbF6]- reveals that the Cr-Cr separation is 3.185(8) Angstrom which is 0.456 Angstrom longer than the neutral complex; magnetic susceptibility studies show that these 26-electron multidecker cations in these salts undergo spin crossovers at 33 and 23 K respectively.
