title: [Spectra of the complexes of zinc salts with AMP].
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.
