Synthesis of a series of Ni(dmit)2 compounds with (methylated) guanidinium cations. Comparison of structures and properties

Abstract

Abstract A series of [cation][Ni(dmit) 2 ] 2 compounds was synthesized with (methylated) guanidinium cations of the type C(N(CH 3 ) 2 ) x (NH 2 ) 3–x (x = 0, 1, 2, 3). The crystal structure of all compounds was resolved and the intermolecular orbital overlap integrals were calculated. The conductivity of the compounds was measured from 300-100 K. All compounds behave as semiconductors in this temperature range.
