Reactions of [M(CP*)Cl(mu-Cl)](2) (M = Ir(1a); M = Rh(1b)) with tridentate ligands tpt (tpt = 2,4,6-tripyridyl- 1,3,5-triazine) gave the corresponding trinuclear complexes [M-3(CP*)(3)(mu(3)-4-tpt-kappa N)Cl-6] (M = Ir(2a); M = Rh(2b)), which can be converted into hexanuclear complexes [M-6(CP*)(6)(mu(3)-4-tpt-kappa N)(2)(mu-Cl)(6)](O3SCF3)(6) (M = Ir(3a); M = Rh(3b)) by treatment with AgO3SCF3, respectively. X-ray of 3b revealed that each of six pentamethylcyclopentadienyl metal moieties was connected by two p-Cl-bridged atoms and a tridentate ligand to construct a cation triangular metallo-prism cavity with the volume of about 273 angstrom(3) based on the distance of the two triazine moieties is 3.62 angstrom.
