Synthesis, Crystal Structure and Physical Properties of Charge Transfer Coordination Complex, [Pt(H2DAG)(HDAG)][Ni(dmit)2].1/2H2O.CH3CN.CH3OH

Abstract

Abstract A low-dimensional charge transfer coordination complex, [Pt(H2dag)(Hdag)][Ni(dmit)2].1/2H2O.CH3CN.CH3OH (H2dag=diamino-glyoxime; dmit=1,3-dithiol-2-thione-4,5-dithiolate) has been synthesized. In the crystal, [Pt(H2dag)(Hdag)] molecules and [Ni(dmit)2] molecules are dimerized, respectively, and the dimerized molecules are stacked alternatively, forming a linear chain structure. The intermolecular S … S contacts between [Ni(dmit)2] molecules in the neighboring linear chains are observed, and moreover intermolecular hydrogen-bonds between S of dmit and H of dag ligands in the neighboring linear chains are also observed, resulting in the two-dimensional network. Single-crystal electrical conductivity, absorption spectrum and magnetic susceptibility have been measured and their results are discussed.
