Structural and magnetic properties of some AgF+ Salts

Compressed Octahedral Coordination in Chain Compounds Containing Divalent Copper: Structure and Magnetic Properties of CuFAsF6 and CsCuAlF6

“…74) with a = 10.732(5), b = 6.941(3), c = 6.814(3) , and Z = 4. It should be noted that, although the unit cell constants are similar to those found for AgFAsF 6 type compounds, [10,11] the structural arrangement is different. The structure can be described in terms of one-dimensional infinite 6 .…”

“…On the other hand a flattened pentagonal bipyramid has been found for AgFMF 6 with M = As, Ir, Au. [10,11,12] For instance, in AgFAsF 6 the distances are the following: two AgÀF at 2.00 and five AgÀF in the 2.39-2.44 range. The resulting near-to-linear coordination is alternatively attributable to the occupancy of the d z 2 orbital by the unpaired electron.…”

Silverland: the Realm of Compounds of Divalent Silver—and Why They are Interesting

“…Simultaneously, the former exhibit more dramatic J dependence on the Ag-F-Ag angle, which is not unexpected [73]; bending of the F bridge in the d(z 2 ) 1 system leads to a dramatic loss of overlap of "linear" d(z 2 ) and p(z) valence orbitals. However, old data from Bartlett and colleagues [75] pointed to the metallic nature of AgFBF 4 and Pauli paramagnetism at high temperatures. It seemed that this case may be similar to that of KAgF 3 (described above) which was erroneously considered to be metallic but turned out to be very strongly coupled 1D AFM; in any case, the discrepancy called for an explanation.…”

Synthesis, structure, and reactivity of high oxidation state silver fluorides and related compounds

“…Dry O2 was introduced and consumed as the red RhF6 warmed, forming 02RhF6. After removing the aHF under vacuum and drying the product for 2.5 h, a red-brown 02RhF6 (16 mg, 0.062 mmol, yield = 18%) was recovered, as confirmed by X-ray powder photography (cubic, a, = 10.18 (2) A, see Table 4.1 1. In the DFULAB, u t F 6 (1 12 mg, 0.321 mmol) and KAgF4 (161 mg, 0.724 mmol)…”

“…AgFAsF, + AsF, % Ag: : l v + 2AsF; (2) With the stronger fluoro-acids, SbF5 and BiF5, two equivalents of acid will bring one equivalent of AgF2 into solution, and in those cases, the Ag(MF,), salts are recovered on removal of aHF. Therefore, Ag : : , v can be easily and reproducibly generated.…”
