Synthesis and Crystal Structure of Zn(Ⅱ) Complex Constructed from 2,3,5,6-Tetramethlytetrephalic Acid
Abstract
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=1.219 80(9)nM,b=1.294 63(10)nM,C=1.784 71(13)nM,V=2.749 4(4)nM3,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) }n(tmbdc = 2,3,5,6-tetramethylbenzenedicarboxylate) 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) nm3,Z= 4.The methyl substituents result in the formation of the hydrophobic 1D chain structure of the title complex.
