摘要

The title phosphanegold(I) thiol#173;ate compound, Au(C9H9N2O3S)(C21H21P), is a second monoclinic polymorph (space group P21/c) that complements a previously reported Cc polymorph Broker amp; Tiekink (2008). Acta Cryst. E64, m1582. An SP donor set defines an approximately linear geometry about the gold atom in both forms. The key distinguishing feature between the present structure and the previously reported polymorph rests with the relative disposition of the thiol#173;ate ligand. In the title compound, the orientation is such to place the oxygen atom in close contact with the gold atom Au#8943;O = 2.915#8197;(2)#8197;#197;, in contrast to the aryl ring in the original polymorph. In the crystal, linear supra#173;molecular chains along the a-axis direction mediated by C#8211;H#8943;#960; and nitro-O#8943;#960; inter#173;actions are found. These pack with no directional inter#173;actions between them. The analysis of the Hirshfeld surfaces for both forms of Au(C9H9N3O3S)(C21H21P) indicates quite distinctive inter#173;action profiles relating to the differences in inter#173;molecular contacts found in their respective crystals.
