The structure of K3H(SO4)(2) is found to be monoclinic with space group C2/
c based on analogy of the powder X-ray diffraction pattern with that of the
Rb3H(SO4)(2). The lattice parameters are a=14.6984(7), b=5.6840(2), c=9.78
34(5) Angstrom, and beta=103.004(5)degrees Vol=796.39(5); D-x=2.589 g cm(-3
), Z=4, and I/I-cor=1.30. (C) 1999 International Centre for Diffraction Dat
