Three acidic sodium sulfates have been synthesized from the system sod
ium sulfate/sulfuric acid and have been crystallographically character
ized. Na(H3O)(HSO4)(2) (A) crystallizes in the space group P2(i)/c wit
h the unit cell parameters a = 6.974(2), b = 13.086(2), c = 8.080(3) A
ngstrom, beta = 105.90(4)degrees, V = 709.1; Angstrom 3, Z = 4. Na-2(H
SO4)2(H2SO4) (B) is orthorhombic (space group Pna2(i)) with the unit c
ell parameters a = 9.970(2), b = 6.951(1), c = 13.949(3) Angstrom, V =
966.7 Angstrom(3) and Z = 4. Na(HSO4)(H2SO4)(2) (C) crystallizes in t
he triclinic space group P1 with the unit cell parameters a = 5.084(1)
, b = 8.746(1), c = 11.765(3) Angstrom, alpha = 68.86(2)degrees, beta
= 88.44(2)degrees, gamma = 88.97(2)degrees, V = 487.8 Angstrom 3 and Z
= 2. All three compounds contain SO4 tetrahedra as HSO4- anions and a
dditionally in B and C in form of H2SO4 molecules.
