摘　　要：Single crystals of two Schiff base compounds 1 and 2 derived from 1-amino-2-hydroxypropane were obtained via condensation reaction of an amine and a reactive carbonyl group. The compounds were characterized by elemental analysis, IR and single-crystal X-ray diffraction. Compound 1(C(10)H(13)NO2) crystallizes in the monoclinic system, space group P21 with a = 4.487(9), b = 10.913(2), c = 9.886(19) ?, β = 97.823(3)o, V = 479.59(16) ?~3, Z = 2, Mr = 179.21, Dc = 1.241 g/cm^3, F(000) = 192, GOOF = 1.005, μ = 0.087 mm^(-1), the final R = 0.0328 and wR = 0.0738 for 1721 observed reflections with I > 2σ(I). Compound 2(C(14)H(20)N2O2) crystallizes in orthorhombic system, space group Pbca with a = 6.295(2), b = 7.290(3), c = 30.519(11) ?, V = 1400.5(9)?~3, Z = 8, Mr = 248.32, Dc = 1.178 g/cm^3, F(000) = 536, GOOF = 1.125, μ = 0.079 mm^(-1), the final R = 0.0871 and w R = 0.1748 for 1307 observed reflections with I > 2σ(I). Compound 1 exhibits a 3D supramolecular structure and compound 2 show a 3D supramolecular structure under hydrogen bonding interactions. Furthermore, the infrared stealthy performance of two Schiff base compounds and their Fe(Ⅲ) complexes were studied. The results show that their Fe(Ⅲ) complexes show lower infrared emissivity than corresponding Schiff base compounds, and the lowest infrared emissivity reaches to 0.657.
