The synthesis and characterisation of the mercury(II) complexes [RHg(SePiPr2)2N}] [R = methyl (2a), ethyl (3a), thienyl (T) (4a), 2-selenyl (SL) (5a) and phenyl (6a)], prepared by the reaction of the sodium salt of NH(SePiPr2)2 (1a) with the appropriate alkyl/aryl mercury halide in methanol are reported. Results are compared and contrasted to the corresponding sulfur analogues [RHg(SPiPr2)2N}] [R
汞(II)配合物[RHg (SeP i Pr 2)2 N}]的合成与表征[R =甲基(2a),乙基(3a),噻吩基(T)(4a),2-硒基(SL)(5a)和苯基(6a)],由钠盐NH(SeP i Pr 2)2 (1a)与合适的烷基/芳基卤化汞甲醇被报道。将结果与相应的硫类似物[RHg (SP i Pr 2)2 N}] [R = T(4b),SL(5b)和Ph(6b)]进行比较和对比,并对这些新化合物进行了评估,经过热重分析质谱法作为潜在的前体,并用粉末X射线衍射法鉴定固态产物。对称复合物Hg [(SeP i Pr 2)2 N] 2 7a和二(2-硒烯基)汞([SLHg (SeP i Pr 2)2 N}的对称产物之一)的固态结构] 5a在溶液中,已经由单晶X射线晶体学。
