摘　　要：合成了标题Schiff碱并获得了其单晶，化学式为射线单晶衍射分析，该晶体属于单斜晶系，空间群P21/c，晶胞参数：可观测衍射点数1014个。晶体中分子以氢键结合形成二聚体。The title Schiff base (C17H18N2O3, Mr= 298. 3) was prepared by condensation reaction be-tween salicylic aldehyde and 1, 3-diamino-2-propanol,and its single crystals were obtained. Thecrystal belongs to monoclinic system, space group P21/c with cell parameters: α= 17. 83O (4), b= 5. 641 (1), c= 16. 319(4) , β= 109. 14(1), V= 1550. 9(6), Z= 4, D= 1. 278 g/cm3,R= 0. 0694,Rw= 0. 085. The crystal structure shows that two molecules of the title Schiff baseare linked together centro-symmetrically by the hydrogen bonds with bond length of 2. 5 .
