[(CF3)4Au2(C5H5N)2] - a new alkyl gold(II) derivative with a very short Au-Au bond

A new gold(II) species [(CF3)(4)Au-2(C5H5N)(2)] with a very short unsupported Au-Au bond (250.62(9) pm) was generated by photo irradiation of a silver aurate, [Ag(Py)(2)][Au(CF3)(2)], unambiguously characterized by F-19 and Ag-109 NMR studies.
