Syntheses and crystal structure of dinuclear zinc complex with Schiff base ligand containing N, O and S dornors

A compartmental Schiff base ligand H(3)L(L(3-) = C11H11N6OS23-) has been synthesized and characterized by elemental analyses, H-1 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. [Zn(2)L(OH)(py)(2)](py)(2), P2(1)/c, a = 0.9195(1), b = 2.3334(6), c = 1.6111(3), beta = 93.99(1)degrees, Z = 4. The structure was solved by direct method. The refinement converges with R = 0.066 and R(w) = 0.070 based on 2028 reflections with I greater than or equal to 3 sigma(I). The results indicate that between two zinc atoms exist two mu(2) - 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.
