Self-assembly of [Bu4N][M(qdt)2] [qdt = Quinoxaline-2,3-Dithiolate; M = Au and Cu] in a 2D Network via Combination of C-H...M and C-H...S Interactions

The compounds [Bu4N][M(qdt)2] (M = Au 1 and M = Cu 2) have been prepared and characterized by X-ray diffraction studies. Complexes 1 and 2 are isomorph and their structure consists of a two-dimensional intermolecular cation-anion network with the [Bu4N] cation acting as a four H-bonded bridging ligand.
