The quadridentate selenoether, 1,3-bis(methylselenoethylseleno)propane, (bsep), has been synthesised from the newly prepared propane-1,3-diselenol, 2-chloroethyl methyl selenide, and sodium methoxide. The ligand forms only insoluble [Pd2(Se4)X4](X = Cl, Br, or I) complexes on reaction with sodium tetrahalogenopalladates(II) and with nickel(II) iodide forms the polymeric octahedral [Ni2(Se4)I4]. The
由新制备的丙烷-1,3-二甲苯酚,2-氯乙基甲基硒化物和甲醇钠合成了四齿硒醚1,3-双(甲基硒乙基硒基)丙烷(bsep)。在与四卤化钯酸钠(II)和碘化镍(II)的反应中,配体仅形成不溶的[Pd 2(Se 4)X 4 ](X = Cl,Br或I)络合物,形成聚合的八面体[Ni 2(Se 4)I 4 ]。将bsep的行为与类似的四硫醚的行为进行比较。聚合[NiL'] n和[PdL'] n通过丙烷-1,3-二甲苯酚(L'H 2)以及镍(II)和钯(II)盐。
