Abstract
The structure of (K0.967(NH4)0.033)3H(SO4)2 crystals, belonging to the K3H(SO4)2–(NH4)3H(SO4)2–H2O salt system, has been investigated by X-ray structural analysis. The room-temperature characteristics of the atomic structure of these crystals are found to be as follows: sp. gr. C2/c, Z = 4, a = 14.7025(4) Å, b = 5.6859(2) Å, c = 9.7885(3) Å, and R/wR = 0.021/0.030%. The thermal and optical properties of (K,NH4)3H(SO4)2 and K3H(SO4)2 single crystals have been investigated and compared in a temperature range of 295–500 K.
