摘要：

Structure analysis of K3D(SO4)2 was performed by X-ray diffraction at room temperature. Cell parameters were obtained as a=9.787(3) Å, b = 5.682(2) Å, c= 14.697(4) Å, α= 103.00(2)° with a space group A2/a, Z=4. Excess electrons were found on a differential Fourier map around a center of inversion. The structure is isomorphous to that of K3H(SO4)2 reported by Noda et al., and the deuterium atoms take the disordered state at room temperature. Obtained hydrogen bond character such as ROO=2.519(2) Å and RDD=0.66(8) Å were compared with those of K3H(SO4)2 in connection with a geometrical isotope effect. © 1990, THE PHYSICAL SOCIETY OF JAPAN.
