摘　　要：A mixed complex [Zn（C5H6N2）（HL）2] （C5H6N2 = 2-aminopyridine, H2L = acetylacetone） has been synthesized and characterized by IR, elemental analysis and X-ray single-crystal diffraction analysis. The crystal belongs to monoclinic, space group P21/c with a = 7.4490（15）, b = 8.2650（17）, c = 27.615（6） A°, β= 101.69（3）°, V = 1664.9（6）A°^3, Z = 4, Mr = 357.70, Dc = 1.427 g/cm^3, F（000） = 744, μ = 1.493 mm^-1, R = 0.0309 and wR = 0.0771. The Zn（Ⅱ） is coordinated by one nitrogen atom from 2-aminopyridine and four oxygen atoms from two acetylacetone anions to furnish a distorted square pyramid geometry. The complex forms a three-dimensional network through intermolecular hydrogen bonds.A mixed complex [Zn（C5H6N2）（HL）2] （C5H6N2 = 2-aminopyridine, H2L = acetylacetone） has been synthesized and characterized by IR, elemental analysis and X-ray single-crystal diffraction analysis.
