The crystal structures of two complexes have been determined by X-ray diffraction as: complex (11) is distorted octahedron configuration,α=15. 9002 (6), b=16. 2413 (5), c=23. 4401 (8)〓,β=90°, V=6053. 2 (4)〓, Z=8 and R=0.0531; complex (8) is trigonal bipyramidal configuration,α=9. 3476 (8), b=17. 4236 (13), c=9. 7836 (8)〓,β=91. 197 (3)°, V=1593. 1 (2)〓, Z=2 and R=0.0325, which shows that three secondary amine groups (N-1, N-2, N-3) of the glycosylamine ligand forms the equatorial plane, and the tertiary amine (N-4) and one Cl〓 are pointed on the apical positions.

分别对其进行X-ray衍射分析可以得出：配合物(11)的晶体数据为α=15.9002(6)，b=16.2413(5)，c=23.4401(8)〓，β=90°，V=6053.2(4)〓，Z=8 and R=0.0531，为畸变的八面体构型，而配合物(8)中，α=9.3476(8)，b=17.4236(13)，c=9.7836(8)〓，β=91.197(3)°，V=1593.1(2)〓，Z=2 andR=0.0325，为三角双锥构型，糖胺配体的三个氮原子（N-1，N-2，N-3）位于赤道平面上，而另外一个氮原子（N-4）和一个Cl〓位于轴向上。

Four new salicylaldehyde derivatives with a glucose or mannose moiety were synthesized with 2-tert-butylphenol or 4-tert-butylphenol as the starting material, followed by the formylation, chloromethylation, nucleophilic substitution reaction with the desired carbohydrate. The salicylaldehyde derivatives condensed with ethylenediamine to give the Schiff bases, which coordinated with Mn to afford four novel sugar-based Salen Mn complexes.
