Packing diagram of compound 2 viewed parallel to the c axis in the region z ≃ 0.25. For all packing diagrams, hydrogen atoms bonded to carbon are omitted for clarity. Thin dashed lines indicate hydrogen bonds or Au1⋯Br2 interactions; thick dashed lines indicate aurophilic interactions. Note that the [AuBr(pyr)] molecules (involving Au1) are viewed end-on. Labelled atoms belong to the asymmetric unit. |
