Solvothermal Synthesis of Alkline Met al Selenides Cs2PdSe16 and Studies of Thermal Stabilities

Abstract

Abstract: The solvothermal technique was used for the synthesis of Cs₂PdSe₁₆ and the crystal structure was determined by single crystal X-ray diffraction methods. Cs₂PdSe₁₆ crystallizes in the tetragonal, space group P4b₂b₂ with a =1.2601(2) nm, b =1.2601(2) nm, c =0.7044(1) nm, V =1.1185(3) nm³, Z=2, R=0.0514, wR =0.0991. The crystal structure consists of two dimensional layers of alternate layers of [CsPd(Se 4)₂]^- and [CsSe₈]⁺. DSCresult indicates its decomposition temperature at 334 ℃.

Key words: Met al selenides, Crystal structure, Inorganic polymer, Solvothermal technique
