摘要
The low-temperature crystal structure of Cd(CN), 2/3H(2)O .t-BuOH (230 K) is reported, Pbcm, a = 8,694(1), b = 16,908(4), c = 21.157(3) Angstrom. 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/H2O system is much better defined at low temperature and this new insight together with solid-state NMR data afford an improved model of the room temperature structure, which is now reported in the space group Cmmm.
