Supramolecular chemistry of [M(CO) ₃ (µ ₃ -OH)] ₄ (M = Mn, Re): spontaneous strict self-assembly of distorted super-diamondoid networks that are capable of enclathrating acetonitrile

Cocrystallization of [M(CO)3(µ3-OH)]4(M = Mn, Re) with the linear difunctional H-bond acceptor molecules 1,4-diaminobenzene and 4,4′-bipyridyl affords, respectively, twofold and fourfold tetragonally distorted super-diamondoid networks that contain microchannels which enclathrate acetonitrile.
