以有机溶剂热生长技术(solvothermaltechnique)，即在180℃乙二胺(en)溶液中，以MnCl~3，PdCl~2，K~2Se在密闭容器中反应7d，制备出新的硫族化合物[Mn(en)~3]PdSe~2，其阴离子基团为[PdSe~2]^2^-，阳离子基团为过渡金属Mn与乙二胺(en)的配合物：[Mn(en)~3]^2^+。以单晶X射线衍射技术解得该晶体结构属正交晶系，空间群为Pbcn，[Mn(en)~3]PdSe~2(Ⅰ)的晶胞数据：a=1.1484(2)，b=1.5057(3)，c=0.93622(19)nm，Z=4。

[Mn(en)~3]PdSe~2(Ⅰ) has been synthesized at 180℃ by solvothermal technique using K~2Se, MnCl~2, PdCl~2 as starting materials and ethylenediamine as solvent reacting for 7 days. Ⅰ shows an isolated structure containing a Zintl anion, [PdSe~2]^2^- and a complex cation, [Mn(en)~3]^2^+. The crystal structure has been determined by single crystal X-ray diffraction techniques. Ⅰ belongs to the orthorhombic, space group Pbcn with unit cell dimensions: a=1.1484(2), b=1.5057(3), c=0.93622(19)nm, V=1.6188(6)nm^3, Z=4.
