报道了固配化合物Zn(p-DMABA)~2Cl~2(p-DMABA=N,N'-对二甲胺基苯甲醛)的低热固相合成，并用红外光谱、拉曼光谱、荧光光谱、差热热失重分析对产物进行了表征。结果表明p-DMABA是通过羰基氧原子与金属锌离子配位的。用粉末X射线衍射仪惧了衍射数据，并对衍射数据进行了指标化，指标化结果如下：Zn(p-DMABA)~2Cl~2为单斜晶系，空间群为P2~111(4)，晶胞参数：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。

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).
