Abstract

The ternary selenides Cs₂Pd₃Se₄, Rb₂Pd₃Se₄ and K₂Pd₃Se₄ have been prepared by fusion reactions of alkali carbonates with palladium and selenium at 850°C. According to X-ray powder patterns (Guinier-Simon technique) Cs₂Pd₃Se₄ is monoclinic with α= 6,49₃ Å, b =14,20₄Å, c = 6,41₄Å, β=120,41_° and is isotypic with Cs₂Pd₃S₄ (C 2/m, No. 12). Rb₂Pd₃Se₄ and K₂Pd₃Se₄ are orthorhombic and isotypic with K₂Pd₃S₄ (Fddd, No. 70). Rb₂Pd₃Se₄: α=11,07₆ Å, b = 27,09₂ Å, c= 6,35₃ Å; K₂Pd₃Se₄: a= 10,95₄ Å, b = 26,19₆ A, c = 6,31₇ Å.
