摘要：

Synthesis of single crystals of Cd(OH)CI and Cu(OH)CI allowed us to revise the structure of these hydroxychlorides and confirm their space group: P6(3)mc (R = 0.041; R-w = 0.050) for Cd(OH)CI and P2(1)/c (R = 0.051; R-w = 0.069) for Cu(OH)CI. Positions of hydrogen atoms mere determined and an hypothesis of hydrogen bonds is discussed in relation to the infrared spectra, A comparison of the structures shows that an isomorphism is not possible between the two compounds, due to the important Jahn-Teller effect of divalent copper. On the other hand, a structural relationship exists between Cd(OH)CI and beta-Cd(OH)(2), which belongs to the brucite-type family. (C) 2000 Academic Press.
