采用扩散法,通过硝酸锌和四甲基对苯二甲酸反应,合成配合物{[Zn(C12H12O4)(DMSO)2]·2(DMSO)}n,并经元素分析和X射线单晶衍射法证实。配合物属单斜晶系,空间群为C2/c,晶体学参数:a=1.21980(9)nm,b=1.29463(10)nm,c=1.78471(13)nm,V=2.7494(4)nm^3,Z=4。甲基取代基导致标题化合物为一维疏水链状结构。
The complex { [Zn(tmbdc) (DMSO)2] · 2(DMSO) },(tmbdc = 2,3,5,6 - tetramethyl- benzenedicarboxylate) is synthesized with 2,3,5,6 - tetramethlytetrephalic acid and Zn ( NO3 ) 2 · 6H2O by means of diffusion. The crystal structure is confirmed by elemental analysis and X - ray single crystal diffraction. The title complex belongs to monoclinic system with space group C2/c, cell parameters: a = 1. 219 80 (9) nm, b = 1. 294 63 (10) nm, c = 1. 784 71 (13)nm, V= 2. 749 4(4) nm^3, Z = 4. The methyl substituents result in the formation of the hydrophobic 1D chain structure Of the title complex.
