T. Kitazawa et al., STRUCTURAL CHARACTERIZATION OF INFINITE 3-DIMENSIONAL [CD4(CN)9]-ION, Journal of the Chemical Society, Chemical Communications, (24), 1993, pp. 1855-1856
Single crystal X-ray determination reveals the first example of a mine
ralomimetic [Cd4(CN)9]- open framework consisting of interconnected te
trahedral and octahedral cadmium centres in the ratio 3:1, while solid
state Cd-113 NMR spectroscopy indicates that some of the bridged cyan
o groups between the Cd atoms are disordered.
