chlorides (MCl2) with tripiperidinophosphine chalcogenides (Pip3PE) produces new dimer species (1–6) of the formula [MCl2(Pip3PE)]2 (Pip = piperidinyl; E = S or Se; M = Hg, Cd or Zn). These coordination complexes were characterized by elemental analysis, IR, multinuclear (31P, 113Cd and 199Hg) NMR spectroscopy and single crystal X-ray analysis. Compounds 1–6 exist as centrosymmetric homobimetallic dimers,
摘要金属氯化物(MCl2)与三联吡啶膦硫属元素化物(Pip3PE)反应生成了新的式[MCl2(Pip3PE)] 2的二聚体(1-6)(Pip =哌啶基; E = S或Se; M = Hg,Cd或锌)。这些配位化合物的特征在于元素分析,红外光谱,多核(31P,113Cd和199Hg)NMR光谱和单晶X射线分析。化合物1-6以中心对称的同双金属二聚体[M(µ-Cl)Cl(Pip3PE)] 2的形式存在。每个二聚体包含两个μ2-氯原子和两个末端M Cl键。Pip3PE的E原子形成末端ME键S; 2.305(11); Se:2.412(6)-2.589(15)A},因此围绕每个金属中心的几何形状是四面体变形的,四面体键角范围为102.83(3)°至113.32(3)°。P Se键的长度为2.183(9)–2。与游离配体[2.1090(4)A]相比,硒化物配合物中的205(2)A略长。对结果进行了
