Synthesis and characterization of the hexagonal prismatic cage {THF⊂[PhB(CN) 3 ] 6 [Cp*Rh] 6 } 6+

Condensation of [Cp*Rh(CH(3)NO(2))(n)](2+) and the tricyanoborate [PhB(CN)(3)](-) affords the hexagonal bipyramidal cage [[PhB(CN)(3)](6)[Cp*Rh](6)](6+), demonstrating that tetrahedral tricyanide building blocks can lead to novel cage structures.
