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.
