A new zinc complex compound of formula 2,6-CH32-C6H3NH32ZnCl4. 2H2O has been prepared and characterized by X-ray crystallography, thermal analysis and IR spectroscopy. The complex crystallizes in the monoclinic space group P21-a with a minimal tetrahedral distortion of the ZnCl4

ion, a = 7.4481 Å, b = 38.4863 Å, c = 8.2981 Å, β= 112.521 °, V = 2197.44 Å

and Z = 4. The crystal structure was solved and refined to R = 0.047 with 3270 independent reflections. It can be described by inorganic layers of ZnCl4.H2O2

parallel to 010 plane, between which the 2,6-xylidinium cations are located. The grouping is maintained by different types of interactions electrostatic, H-bonds, Van der Walls and π-π stacking. A characterization of this compound by thermal analysis and IR spectroscopy are also reported.
