“…By con- [32,33] has this band again at 903 cm −1 , the small shift relative to CsReO 4 (910 cm −1 ) being probably due to hydrogen bonding O···H-N to the NH 2 groups of the en ligand of the cation. In ionic liquids with various imidazolium cations having only C-H···O hydrogen bonding capabilities, the ν 3 band of the perrhenate anion is also found in the range 902 -913 cm −1 [27,28].…”

“…Similar characteristics have later been found for the corresponding germanium [24] and tin compounds [25,26], the latter being aggregated through an increase in the coordination number of the tin atoms and with the ReO 4 units functioning as bridging units employing two of their four oxygen atoms. This work was complemented by diorganoindium and other organometallic perrhenates, but structural details have not become available for most cases [27,28].…”

Dedicated to Professor Bernd Krebs on the occasion of his 75 th birthdayBis(triphenylphosphine)gold(I) perrhenate [Ph 3 PAuPPh 3 ] + ReO 4 − has been prepared in high yield from Ph 3 PAuCl, Ph 3 P and AgReO 4 in a mixed solvent. The compound is stable in air and decomposes at 235 • C. In the crystal structure, the two independent perrhenate anions are not approaching the gold centers of the two independent cations, but weak interionic interactions are entertained via π-π stacking of phenyl groups and C-H···O contacts. As three-blade chiral rotors, the Ph 3 P ligands of the cations are in a staggered conformation at the gold atoms with only slightly bent P-Au-P axes. IR and NMR data show no anomalies and are close to those of alkali or onium perrhenates.

“…22 Similar overall characteristics were found for organogermanium, -tin and -indium perrhenates. [23][24][25][26][27] The combination of perrhenate with the heavy coinage metals, Ag and Au, is poorly presented in the literature. Contrary to silver(I) perrhenate AgReO 4 , 5,28 gold(I) perrhenate AuReO 4 is still an unknown compound.…”

The 1 : 4 and 1 : 2 complexes of silver perrhenate and triphenylphosphine, [(Ph3P)4Ag](+) ReO4(-) and [(Ph3P)2AgReO4]2, have been prepared and their structures determined in the solid state by X-ray diffraction. The former is composed of independent ions, while in the latter the ions are aggregated into cyclic dimers. The silver centers are tetracoordinated including contact with two bridging perrhenate anions, setting this structure apart from that of its gold analogue [(Ph3P)2Au](+) ReO4(-) where the gold centers are strictly two-coordinate.
