本文合成了具有隔室构造的Schiff碱配体H3L(L^3^-=C11H11N6OS2^3^-), 并对其进行了元素分析, IR, ^1H NMR和MS等项表征。制备了该配体的分别由醋酸根和吡啶分子协配的两种锌的双核配合物, 对后者进行了X射线单晶结构分析。[Zn2L(OH)(py)2](py)2, P21/c, a=0.9195(1), b=2.3334(6), c=1.6111(3)nm,β=93.99(1)°, Z=4。结构用直接法解得, 最终的R=0.066。测定的结果表明,两锌原子间存在酚氧和羟基的两μ2-O-桥, 每个五配位的锌均具有四方锥型的配位构型。

A compartmental Schiff base ligand H3L (L^3^-=C11H11N6OS2^3^-) has been synthesized and characterized by elemental analysis, ^1H NMR, IR and MS as well as etc.. Its dinuclear zinc complex, which are co- coordinated by acetate radicals and pyridine molecules respectively, have been prepared. For the later the single crystal structure has been determinated by X-ray diffraction. [Zn2L(OH)(py)2](py)2, P21/c, a=0.9195(1), b=2.3334(6), c=1.6111(3), β=93.99(1)°, Z=4. The structure was solved by direct method. The refinement converges with R=0.066 and Rw=0.070 based on 2028 reflections with I>=3σ(I). The results indicate that between two zinc atoms exist two μ2-O^- bridges formed by a phenolic oxygen atom and a hydroxy group in the lattice, respectively; and every five-coordinate zinc atom possesses a square pyramidal construction.
