Abstract
The complex HMEDA[Ni(dmit)(2)](2)I (HMEDA = Hexamethylethylenediammonium) h as been prepared. A single X-ray crystal structure analysis reveals that th ere are short S ... S contacts between Ni(dmit)(2) dimmers. The monoclinic system, space group p2/n, has cell dimensions: a = 11.710(3) Angstrom, b = 22.559(5) Angstrom, c = 7.374(2) Angstrom, beta = 93.000(3)(0), V = 1945.3( 8) Angstrom(3), z = 4. Full-matrix least-squares refinement, based on 2989 reflections converged at R = 0.0686. The conductivity of this salt at room temperature is 0.1 S cm(-1) and it shows semiconducting behavior from 20 to 300 K. (C) 1998 Elsevier Science S.A. All rights reserved.
