摘要

合成了两个新的与丙二酸二乙酯阴离子和4,4′-联吡啶混合配体的三维金属（MnII, CuII）配合物，并用红外光谱和x射线衍射对其进行了表征。配合物[Mn(HEt2mal)2(bpy)(H2O)2]n (1) （H2Et2mal为二乙基丙二酸，bpy为4,4′-联吡啶）含有六配位金属原子，具有链式结构。在配合物1的结构中，通过氢键形成两个互穿框架。配位聚合物{[Cu2(Et2mal)2(bpy)(H2O)]•6 H2O}n(2)含有四坐标和五坐标铜（ii）阳离子，并形成垂直于结晶轴a的无限层。

Synthesis and structure of copper(ii) and manganese(ii) diethylmalonates with 4,4′-bipyridine

Two new mixed-ligand 3d-metal (Mn^II, Cu^II) coordination compounds with diethylmalonate anions and 4,4′-bipyridine were synthesized and characterized by IR spectroscopy and X-ray diffraction. The complex [Mn(HEt₂mal)₂(bpy)(H₂O)₂]_n (1) (H₂Et₂mal is diethylmalonic acid, bpy is 4,4′-bipyridine) contains six-coordinate metal atoms and has a chain structure. In the structure of complex 1, two interpenetrating frameworks are formed through hydrogen bonds. The coordination polymer {[Cu₂(Et₂mal)₂(bpy)(H₂O)]•6 H₂O}_n (2) contains four- and five-coordinate copper(ii) cations and forms infinite layers perpendicular to the crystallographic axis a.
