Abstract

Even though we tried to get a deuterated analogue of K3CaH (PO4)2 we did not have success, therefore we focused on the specters of protiated analogue of the said compound. The structure of K3CaH (PO4)2 is determined by x-ray diffraction. [1]. The compound crystallizes in the monoclinic system (space group C2/m respectively C2h3) with two-unit formulas in the elementary cell. The structure of this compound characterizes with the existence of symmetrical dimers [H(PO4)2], similar like the Mg2KH(PO4)2·15H2O and Mg2KH(AsO4)2·15H2O [7]. The IR and Raman spectra are recorded at room temperature and at the boiling temperature of liquid nitrogen (LNT).
