The crystal and molecular structure of one of the possible conformers of 'the smallest piece of ice' - A solid-state isolation of a hydrogen bonded water hexamer trapped within channels of a crystal of a dirhodium molecule

摘要

Reexamination of our study of [Rh-2(HNOCCH3)(4)(2H2O)] . 3H(2)O (Ahsan, M. Q.; Bernal, I.; Bear, J. L. Inorg. Chem. 1986, 26, 260) showed it to be interesting not just because the dirhodium molecule is an antineoplastic but because it contains a hexameric cluster of waters trapped in Rh-Rh lattice cavities. It may well provide an interesting model for the "smallest piece of ice". [References: 15]
