Guest-dependent [Cd(CN)2]n host structures of cadmium cyanide–alcohol clathrates: two new [Cd(CN)2]n frameworks formed with PrnOH and PriOH guests

Abstract

Crystallization of Cd(CN)₂ from the geometric isomers of propanol, PrⁿOH and PrⁱOH, yielded new cadmium cyanide clathrates whose [Cd(CN)₂]_n frameworks are topologically and geometrically different not only from those of all the previously known cadmium cyanide clathrates but also from each other: the former has both hexagonal and pentagonal channels whereas the latter has only pentagonal channels.
