Abstract The crystal and molecularstructure of hydrophilicN,N-di(2-hydroxyethyl)-N′-benzoylthiourea (H3L4) has been determined. This ligand coordinates to Pt(II), Pd(II) and Ni(II) in a bidentate manner yielding essentially neutral complexes of the type cis-[Pt(H2L4)2]. By contrast, N-(2-hydroexyethyl)-N′-benzoylthiourea (H3L5) behaves like a monodentate thiourea ligand and reacts with Pt(II) to
Hydrogen Bonds in 1,1-Bis(2-hydroxyethyl)-3-benzoylthiourea and its Nickel(II)- and Copper(II)-Chelate Complexes The ligand 1,1-bis(2-hydroxyethyl)-3-benzoylthiourea HL, (1), yields with nickel(II) and copper(II) ions neutral complexes [NiL2], (2), and [CuL2], (3). By X-ray structure analysis and IR spectroscopy different intramolecular hydrogen bonds (OH…O) and (OH…N) could be identified in both equally
1,1-双(2-羟乙基)-3-苯甲酰硫脲及其镍(II)-和铜(II)-螯合物中的氢键配体1,1-双(2-羟乙基)-3-苯甲酰硫脲HL, (1), 镍 (II) 和铜 (II) 离子中性复合物 [NiL2], (2) 和 [CuL2], (3) 的产量。通过 X 射线结构分析和红外光谱,可以在 [NiL2] 分子的两个同等配位的配体中识别出不同的分子内氢键 (OH…O) 和 (OH…N)。为了比较,还估计了 1 和 3 的 X 射线和 IR 数据。
