The ethyl hemiester of carbonic acid is prepared as a pure solid and sublimed to the gas phase, in spite of claims of its instability. FT-IR spectroscopy combined with ab initio calculations reveals a 5 : 1 ratio of the two most stable conformers.

Reaction of [NBu4][Au(C6X5)2] (C6X5 = 3,5-C6Cl2F3, C6Cl5) with AgOClO3 in an Et2O/CH2Cl2 mixture affords [Au2Ag2(C6X5)4(OEt2)2]n [C6X5 = 3,5-C6Cl2F3 (1a), C6Cl5 (1b)]. These compounds react with tetrahydrofuran, acetone, acetonitrile or toluene in solution and in the gas phase (with toluene only in solution) to the new complexes [Au2Ag2(C6X5)4L2]n [L = THF (2a, 2b), (CH3)2CO (3a, 3b), CH3CN (4a, 4b), C7H8 (5a, 5b)]. The crystal structures of 2a and 5a have been determined by X-ray diffraction methods, showing polymeric chains formed by the union of tetranuclear Au2Ag2 units via aurophilic interactions. The thermal stability and the vapochromic behaviour of these complexes have been studied by thermogravimetric analysis (TGA), X-ray powder diffraction and FT-IR spectroscopy
