摘　　要：An aminophenol ligand, N,N,N＇-tri（2-hydroxy-5-methylbenzyl）-l,2-ethanediamine, was prepared through the Marmich reaction, and structurally characterized by NMR, IR, MS and single-crystal X-ray diffraction. The title compound （C26H32N2O3, Mr = 420.54） belongs to the monoclinic system, space group P21/n with a = 8.6233（14）, b = 10.2655（16）, c = 26.017（4） A, β = 95.797（2）°, V = 2291.3（6） A^3, Z = 4, the final R = 0.0461 and wR = 0.1139 for 4267 unique reflections （Rint = 0.028） with 11691 observed ones （I〉 2a（I））.An aminophenol ligand, N,N,N＇-tri（2-hydroxy-5-methylbenzyl）-l,2-ethanediamine, was prepared through the Marmich reaction, and structurally characterized by NMR, IR, MS and single-crystal X-ray diffraction.
