Abstract: The crystal structure of the title compound was determined by X-ray diffractometry.The complex crystallizes in monoclinic space group C2/c with Z= 8. Lattice parametersare: a =25.747(5), b= 8.461(0), c = 17.407(3)Å and β= 105.79(1)°. The structure wassolved by Patterson and Fourier techniques and refined by least-squares to a final R valueof 0.0283. The Zn(Ⅱ) ion is coordinated by three chloroligands and the atom N(1) of thepyrimidine ring of thiamine molecule, forming a slightly distorted tetrahedral coordinationpolyhedron. The average Zn-Cl distance is 2.266Å and the Zn-N bond length is2.042(4)Å.
