“…The HF molecules are coordinated to the rhenium atom through their F atoms, representing the only known example of HF coordinated to rhenium. Several examples in which HF is coordinated to alkaline earth and lanthanide metal cations and to Os(VIII) are also known. The facial arrangement of oxygen atoms is the result of equal competition of the filled p orbitals of the oxygen atoms for the three empty approximately d t 2g orbitals of rhenium .…”

“…This is in agreement with the results obtained in other MF 2 / XF 5 (M = Ca, Sr, Ba; X = As, Sb, Ta, Ru) systems, where the crystallization products from the HF saturated solution always contained HF coordinated to Ca, Sr, or Ba atoms. Some examples are [Ca(HF) n ](AsF 6 ) 2 (n = 1, 6), 47 [Ca(HF) 2 ]-(SbF 6 ) 2 , 48 [Sr(HF) 3 ](TaF 6 ) 2 , 49 [Ba(HF)](RuF 6 ) 2 , 48 and [Ba-(HF)](AsF 6 ) 2 . 50 To date, no crystals of M(XF 6 ) 2 (M = Ca, Sr, Ba; X = As, Sb, Ta, Ru) have been prepared so far.…”

“…F(-H)···F) involved in such bonding are significantly longer than in the case of [HF 2 ] -anion. After the first example La(HF) 2 (AsF 6 ) 3 [8] many other crystal structures of such compounds have been reported [9]. The HF molecules could be bound to transition metals -(HF) 2 ReO 3 F·HF [10], lanthanides -LnF(HF)(BF 4 ) 2 , Ln = Pr, Nd [11] or main group elements -Sr(HF) 3 (TaF 6 ) 3 [12], Tl(HF)F 3 ·AsF 5 ·HF [13].…”
