Triphenyl- n-propylphosphonium bis(2-thioxo-1,3-dithiole-4,5-dithiolato)aurate(III).

In the title complex, (C21H22P)[Au(C3S5)2] or (Ph3C3H7P)[Au(dmit)2] (where Ph3C3H7P is the triphenyl- n-propylphosphonium cation and dmit is the 2-thioxo-1,3-dithiole-4,5-dithiolate anion), the AuIII atom exhibits a square-planar coordination involving four S atoms from two dmit ligands. The [Au(dmit)2]− anions form discrete pairs with a long intermolecular Au...S interaction for each Au atom in the crystal structure. [ABSTRACT FROM AUTHOR]
