Abstract: A novel two-dimensional 18-crown-6 (18-C-6) complex,[Na2(18-C-6)2(H2O)3]-[Ni(dmit)2]2·(18-C-6) (dmit, 4,5-dimercapto-1,3-dithiole-2-thione, C3 S52-) (1) has been synthesized and characterized by elemental analysis, IR spectrum and X-ray diffraction analysis. 1 belongs to triclinic, space group-1 with cell dimensions, a= 13.227(10), b = 12.8421(11), c = 13.8671(12) Å, α =83.715(2),β=88.477(2),γ=71.850(2)o, V= 1904.5(3)Å3. Z=2, Dcalcd = 1.566 g/cm3. F(000) = 932. R1 = 0.0415, wR2 = 0.0805. It consists of one [Na2(18-C-6)2(H2O)3]2+ complex cation, two [Ni(dmit)2] complex anions and one free 18-C-6 molecule. The complex shows two-dimensional structure assembled by S···S and Ni···S weak interactions.
