چکیده
All commercially available reagents were used as received. Solvents were distilled before use. The obtained compounds were fully characterized by standard analytical methods using a Varian Mercury 300 NMR spectrometer for H(300 MHz) and F-NMR spactra (282 MHz) in deuteric solvents. Mass spectrometric data were recorded on Finnigan SSQ 7000 and Thermo Deca XP as EI (70 eV) or ESI. IR spectra were obtained by a PerkinElmer FTIR spectrometer Spektrum 100 in KBr pellets (4000-650 cm) and a CHN-O-Rapid Vario EL from Heraeus was used for elemental analysis. Melting points were taken by a Büchi B-540 without correction.

A hexanuclear gold carbonyl cluster† †Dedicated to Prof. Dr Pablo Espinet on the occasion of his 65th birthday. Abbreviations are defined prior to the Acknowledgements section. As defined in ref. 1, “clusters are molecular units which may contain small or large numbers of similar atoms where there are several short internuclear distances between atom pairs.” This definition is fully compatible with that originally given by F. A. Cotton (ref. 2). ‡ ‡Electronic supplementary information (ESI) available: Experimental procedures, comments on the X-ray structure determinations and 3D Hirschfeld surfaces for the ions constituting the crystal of 4.
