Abstract: 
The reactions of simple Li salts like sulfates, carbonates, and chlorides with fuming sulfuric acid or neat SO3 led to a couple of new acidic Li disulfates with varying H2SO4:SO3 ratios, namely Li-2[S2O7]center dot H2SO4 (orthorhombic, Pca2(1), Z = 4, a = 945.67(8) pm, b = 485.77(4) pm, c = 1793.9(1) pm, V = 824.1(1) x 10(6) pm(3), R-1 (all data) = 0.138, wR(2) (all data) = 0.0380), Li[HS2O7] (monoclinic, Cc, Z = 4, a = 685.87(3) pm, b = 788.49(4) pm, c = 911.48(5) pm, beta = 101.618(2)degrees 1, V = 482.83(4) x 10(6) pm(3), R-1 (all data) = 0.148, wR(2) (all data) = 0.0416), and Li[H(HS2O7)(2)] (monoclinic, P2(1)/n, Z = 2, a = 498.69(2) pm, b = 808.57(3) pm, c = 1297.22(5) pm, beta = 94.875(2)degrees 1, V = 521.18(3) x 10(6) pm(3), R-1 (all data) = 0.157, wR(2) (all data) = 0.0481). The stamping structural feature of these salts are moderate and strong hydrogen bonds linking the anions to chains and layers. Especially for Li[H(HS2O7)(2)] a very strong symmetrical hydrogen bond is found linking two hydrogendisulfate anions via a common hydrogen atom to the new hydrogenium-bis-hydrogendisulfate anion [H(HS2O7)(2)](-).
