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.
