✦ Synopsis

Reactions

between gold pentafluoride and alkali-earth metals fluorides in non-aqueous hydrogen fluoride were investigated.

Ca (AuF6) 2 I Sr(AuF6)2 and Ba(AuF6)2 were identified.

The Raman spectra of the received compounds were examined in crystalline form and in the non-aqueous HF solution.

It was found out, that bis-hexafluoroaurates had high solubility in non-aqueous HF. The Raman spectra of liquid system HF-MII(AuF,)-KrF2 were investigated. The compounds of variable composition on KrF2, where n=1+4 (Ba, Sr) and n=1+3 (Ca) were crystallized from this system, if the solvent were evaporated slowly.
