Trigonal prismatic Cu(i) and Ag(i) pyrazolato nanocage hosts: encapsulation of S8 and hydrocarbon guests†
Abstract
Two neutral hexanuclear trigonal prismatic cage molecules have been synthesized by coupling two planar triangular M3pz3-panels, M = Cu(I) and Ag(I), in eclipsed geometry. The ∼230 Å3 cage volume can be either vacant or occupied by neutral guests. The crystal structures of the M6–cyclohexane and Ag6–S8 host–guest species have been determined.
