The structure of (K{sub 0.967}(NH{sub 4}){sub 0.033}){sub 3}H(SO{sub 4}){sub 2} crystals, belonging to the K{sub 3}H(SO{sub 4}){sub 2}–(NH{sub 4}){sub 3}H(SO{sub 4}){sub 2}–H{sub 2}O 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,NH{sub 4}){sub 3}H(SO{sub 4}){sub 2} and K{sub 3}H(SO{sub 4}){sub 2} single crystals have been investigated and compared in a temperature range of 295–500 K.
