Abstract

The structures of ethyl 2,2-bis{[(benzoylcarbamothioyl)oxy]methyl}propanoate and its 1 : 1 complexes with copper(II) and cobalt(II) ions were determined by electronic absorption, IR, and ¹H and ¹³C NMR spectroscopy and elemental analysis. The coordination entity in the complexes includes oxygen and sulfur atoms of the benzoyl and carbamothioyloxy groups of both ligand branches. The copper(II) ion has octahedral configuration with trigonal distortion, and the cobalt(II) ion has five-coordinate square–pyramidal configuration. The thermal behavior of the title compounds was studied by differential scanning calorimetry and thermogravimetric analysis.

摘要

通过电子吸收，IR，¹ H和¹³ C测定2,2-双{[（（苯甲酰氨基甲硫酰基）氧基]甲基}丙酸乙酯及其与铜（II）和钴（II）离子的1：1配合物的结构NMR光谱和元素分析。配合物中的配位实体包括两个配体分支的苯甲酰基和氨基甲硫酰氧基的氧和硫原子。铜（II）离子具有八面体构型，具有三角形畸变，而钴（II）离子具有五坐标方锥构型。通过差示扫描量热法和热重分析法研究了标题化合物的热行为。
