The coordination complex of a weak ligand, p-dimethylaminobenzaldehyde (p-DMABA), with ZnCl~2 was prepared by a solid state reaction at low temperature (60℃). The final product was characterized by elemental analysis, TGA-DTA, FT-IR, Raman, fluorescence spectroscopy and XRD. The C=O stretching frequency of the title compounds shifted to lower wavenumber upon addition of Zn^+ indicating the formation of a covalent bond between the carbonyl oxygen and the zinc cation. 25 lines (5°<2θ<60°) were indexed to give the unit cell parameters: a=1.5897(2)nm, b=0.7560(4)nm, c=1.0373(1) nm, β=95.23(3)°, V=1.241(2) nm^3. Extinction conditions indicate that the space group is P2~1 11(4).
