| Abstract: | A novel framework K4Ag2Ge3S9·H2O was synthesized solvothermally in the presence of a chelating agent of HSCH2CH(SH)CH2OH. Its structure was determined by single-crystal X-ray diffractometry. This material crystallizes in the orthorhombic space group Pna2(1) (No. 33) with a=14.4524(4) Å, b=9.6339(3) Å, c=16.5636(9) Å, z=4, R1=0.0292, wR2=0.0624 for all data. The structure comprises of adamantane-like clusters [AgGe3S9]5− linked by Ag+ ions to form a open-framework, and potassium ions and water molecules are located in the channels. Its IR and thermal properties were investigated. |
