Abstract: | 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. |
