“…Two Bi2−F3 distances of 2.036 Å are significantly longer, than the others, which range from 1.945 Å to 1.957 Å. The Bi2−F distances are comparable to those in Ag(BiF 6 ) 2 (Bi−F: 2.046 Å, 2.048 Å, 1.944 Å, 1.966 Å, 1.939 Å, 1.940 Å) [17] and to some extent with the distances in Cd(BF 4 )(BiF 6 ) (Bi−F distances: 2.03 Å, 2.02 Å, 1.99 Å (2x), 1.96 Å, 1.94 Å) [18] …”

“…The Bi2À F distances are comparable to those in Ag(BiF 6 ) 2 (BiÀ F: 2.046 Å, 2.048 Å, 1.944 Å, 1.966 Å, 1.939 Å, 1.940 Å) [17] and to some extent with the distances in Cd-(BF 4 )(BiF 6 ) (BiÀ F distances: 2.03 Å, 2.02 Å, 1.99 Å (2x), 1.96 Å, 1.94 Å). [18] Raman spectroscopy is a very useful tool for observing the products with XeF 2 as a ligand to the metal centre. The Raman spectra of [Bi(XeF 2 ) 3 ](BiF 6 ) 3 are shown in Figure 6.…”

“…Vibrations associated with [BiF 6 ] − anions were observed at 588 cm −1 and with the highest intensities in [XeF][BiF 6 ] [13] . Other examples of compounds with [BiF 6 ] − anions such as NF 4 BiF 6 (υ1 of [BiF 6 ] − at 580 cm −1 ) [19] and Cd(BF 4 )(BiF 6 ) (υ(Bi−F): at 584 cm −1 ) [18] show very intense bands at similar positions. From the vibrational point of view, it is also particularly important to look more closely at the part of the spectrum associated with the Xe−F vibrations.…”

Dedicated to late Prof. Rudolf Hoppe on the occasion of his 100 th birthday Main group trivalent metal canter is added to the diverse family of coordination compounds with XeF 2 as a ligand for the first time. [Bi(XeF 2 ) 3 ](BiF 6 ) 3 can be prepared by the direct reaction between BiF 3 , BiF 5 and XeF 2 in anhydrous HF as solvent. The compound is stable at room temperature under inert conditions. In the compound, the same metal is found in two oxidation states: Bi(III) and Bi(V). [Bi(XeF 2 ) 3 ](BiF 6 ) 3 crystalizes in hexagonal space group P 6 2 c at 150 K with a = 10.3296(5) Å, b = 10.3296(5) Å, c = 12.1775(7) Å. The metal centre Bi(III) is coordinated with nine F atoms. Six F atoms from BiF 6 units are located in the corners of the trigonal prism, while the rectangular faces of the trigonal prism are capped with F atoms from three XeF 2 ligands. The Bi(III) centres are connected via Bi(V)F 6 units into the three dimensional network. All three XeF 2 ligands are non-bridging.

Crystal growth from anhydrous hydrogen fluoride solutions of M2+ (M=Cu, Ag) and [AuF6]− gave M(AuF6)2 salts (M=Cu, Ag). Similar attempts to prepare single crystals of the corresponding nickel, zinc and magnesium salts failed. The crystal structure of Cu(AuF6)2 consists of layers of Cu2+ cations connected by [AuF6]− anions, thus forming slabs. Only van der Waals interactions exist between adjacent slabs. The crystal structure of Ag(AuF6)2 consists of a three‐dimensional framework in which Ag+ cations are linked by [AuF6]− anions. Both structures are members of the MII(XVF6)2 family, in which seven different structure types have been observed to date. In the crystal structure of O2(CuF)3(AuF6)4 ⋅ HF, the bridging AuF6 units connect [−Cu−F−Cu−F−]∞ chains to form stacks between which O2+ cations and HF molecules are located.

“…For example, fluoroanions can be used to probe new bonding motifs in organometallic complexes, involving metals that include B [1], Co [2][3][4][5][6], Ga [7], As [1], Cd [8], Pd [9], In [7], Sn [10], and U [11]. One of the most intriguing properties of fluoroanion-containing materials is the ability to solvate HF, which has the potential to provide improved safety and efficiency for synthetic chemistry [7,[11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28].…”
