Title: Syntheses and Crystal Structure of Dinuclear Zinic Complex with Schiff Base Ligand Containing N,O and S Dornors
Abstract: A compartmental Schiff base ligand H3L(L3- = C11H11N6OS23-)has been synthesized and characterized by elemental analyses, 1H NMR, IR and MS as well as etc. . Its dinuclear znic 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 - raydiffraction. [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 withR = 0.066 and Rw = 0.070 based on 2028 reflections with I≥3σ(I).The results indicate thatbetween two zinc atoms exist two u2 - 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.
