Abstract
The crystallographic data for K[NbO(C204)2 (H20h] · 3H20,
NH4[NbO(C204)2 (H20)2] · 2H20, and Rb[NbO(C204)2 (H20)2] · 2H20
has been obtained by X-ray diffraction methods. On the basis of
similar values of unit cell parameters and the same space group
extinctions, an isostructural relationship has been found among
dihydrates of Cs-salt (with known crystal structure from previous
work2) and NH4- and Rb-salts, as well as between trihydrates of
NHrsalt (with crystal structure3 solved previously too) and K-salt.
