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 ℃.
