elemental palladium with H2SeO4 in sealed glass tubes at 350 °C leads to red single crystals of Pd(SeO3) [C2/m, Z = 4, a = 6.788(2), b = 7.030(2), c = 7.008(2) A, β = 118.09(3)°] or to yellow-orange single crystals of Pd(SeO4) [C2/c, Z = 4, a = 8.171(1), b = 5.286(1), c = 8.115(1) A, β = 94.54(1)°]. Yellow-orange single crystals of Pd(Se2O5) [I2/a, Z = 4, a = 7.212(1), b = 5.569(1), c = 12.177(3) A, β = 106
取决于反应条件,元素钯与 H2SeO4 在密封玻璃管中在 350 °C 下反应生成红色单晶 Pd(SeO3) [C2/m, Z = 4, a = 6.788(2), b = 7.030 (2), c = 7.008(2) A, β = 118.09(3)°] 或 Pd(SeO4) 的黄橙色单晶 [C2/c, Z = 4, a = 8.171(1), b = 5.286(1), c = 8.115(1) A, β = 94.54(1)°]。Pd(Se2O5) [I2/a, Z = 4, a = 7.212(1), b = 5.569(1), c = 12.177(3) A, β = 106.84(2)°] 的黄橙色单晶是在反应混合物中加入 SeO3 时得到的。X 射线单晶衍射表明 Pd(SeO3) 由由方形平面配位 Pd2+ 离子和金字塔形 SeO32– 基团形成的层组成。这些层通过涉及硒原
