Abstract
In this work, we show that intramolecular hydrogen bonding can be used to stabilize tri-coordinated phosphane-gold(I) complexes. Two molecular structures of 2-(diphenylphosphino)benzoic acid (L) coordinated to a gold(I) atom were determined by single-crystal X-ray diffraction. The linear L-Au-Br shows a standard linear coordination and dimerizes via hydrogen bonds of the carboxylic acid. Upon addition of two additional phosphane ligands the complex [L3Au]X is formed which is stabilized by three intramolecular -C(O)O-H … X hydrogen bonds as proven by the X-ray structure of the respective chlorido-complex. X-ray powder diffractograms suggest the same structure also for X- = Br- and I-.

期刊介绍:
"Monatshefte für Chemie/Chemical Monthly" was originally conceived as an Austrian journal of chemistry. It has evolved into an international journal covering all branches of chemistry. Featuring the most recent advances in research in analytical chemistry, biochemistry, inorganic, medicinal, organic, physical, structural, and theoretical chemistry, Chemical Monthly publishes refereed original papers and a section entitled "Short Communications". Reviews, symposia in print, and issues devoted to special fields will also be considered.
