【Abstract】 On the basis of the literature, the synthetic method of 2-amino-4,6-dimethoxy-pyrimidine (AMP) was ameliorated and the yield was improved. The complexes of hydrous copper chloride and copper nitrate with AMP in a molar ratio of 1∶2 were prepared through reflux in alcohol. The composition of the complexes Cu(AMP) 2Cl 2(1) and Cu(AMP) 2(NO 3) 2 (2) were determined by chemical and elemental analyses. The bonds between Cu 2+ and AMP were investigated by IR, XPS and 1H NMR, which showed that nitrogen atom in the amino group and one of nitrogen atoms in the pyridine ring coordinated to Cu 2+ in bidentate fashion when NO 3 - in the complex 2 did not participated in the coordination. From the analytical results, it is assumed that Cu 2+ in the complexes 1 and 2 hybridized separately in sp 3d 2 and sp 3 with the coordination number of 6 and 4.更多还原
