摘要

Two cationic pentamethylcyclopentadienyl metal-based hexanuclear complexes with trigonal prismatic architecture have been synthesised through a two-step strategy.The dinuclear complexes[M(eta 5-C5Me5)(mu-Cl)Cl]2(M=rhodium and iridium)react with 2,4,6-tri(pyridm-4-yl)-1,3,5-triazme(tpt)in dichloromethane to give the trinuclear complexes[Rh3(eta 5-C5Me5)3(mu 3-tpt)Cl6](1)and[rr3(eta 5-C5Me5)3(mu 3-tpt)Cl6](2),respectively.Addition of silver triflate to 1 and 2 in dichloromethane connects two identical triangular panels to form the hexanuclear metallo-prismatic cations[Rh6(eta 5-C5Me5)6(mu 3-tpt)2(mu-Cl)6]~(6+)(3)and[Ir6(eta 5-C5Me5)6(mu 3-tpt)2-(mu-Cl)6]~(6+)(4),respectively.Cations 3 and 4 have been isolated as their triflate salts and characterised by ~1H NMR,IR and UV/visible spectroscopy.
