Abstract

The complexes of ZnCl2 and ZnSO4 with AMP in molar ratios of 1:1 and 1:2 were prepared through reflux in alcohol. The compositions of the complexes were determined to be Zn(AMP)2Cl2(A) and Zn(AMP)SO4(B) by chemical and elemental analyses. It was identified via IR analysis for the complexes that nitrogen atom of amino group and one of nitrogen atoms of pyrimidine coordinated to Zn2+ in bidentate fashion. Cl- in the complex of A and SO4(2-) in the complex of B participated in the coordination to Zn2+ and some feedback characteristic was found in the bond of N-->Zn2+, which was proved by XPS spectra. Study on 1H NMR for the complexes showed that two ligands joined the coordination to Zn2+ in the complex of A while one ligand did in the complex of B. Based on the above analyses, the structures of the complexes were presumed.

摘要

通过在醇中回流制备了摩尔比为1:1和1:2的ZnCl₂和ZnSO₄与AMP的配合物。通过化学分析和元素分析确定配合物的组成分别为Zn(AMP)₂Cl₂(A)和Zn(AMP)SO₄(B)。通过对配合物的红外分析确定，氨基的氮原子和嘧啶的一个氮原子以双齿方式与Zn²⁺配位。配合物A中的Cl⁻和配合物B中的SO₄²⁻参与了与Zn²⁺的配位，并且在N→Zn²⁺键中发现了一些反馈特征，这由XPS光谱证明。对配合物的¹H NMR研究表明，在配合物A中有两个配体参与与Zn²⁺的配位，而在配合物B中只有一个配体参与。基于上述分析，推测了配合物的结构。
