✦ Synopsis

The low-temperature crystal structure of Cd(CN) 2 ' 2/3H 2 O ' t-BuOH (230 K) is reported, Pbcm, a ‫؍‬ 8.694(1), b ‫؍‬ 16.908(4), c ‫؍‬ 21.157(3) A > . Although the cell has approximately twice the volume of the previously reported room temperature cell the 3D cadmium-cyanide framework has essentially the same connectivity. The hydrogen bonded t-BuOH/H 2 O system is much better de5ned at low temperature and this new insight together with solid-state NMR data a4ord an improved model of the room temperature structure, which is now reported in the space group Cmmm.
