“…The latter distances are comparable to those of other weak AgÀO interactions, for example, in (OC)Ag[B(OTeF 5 ) 4 (AgÀO 2.324(6), 2.436(6) ä). [19] Interestingly, the local AgO 2 P 2 coordination sphere in 2 is tetrahedral, while that in 3 is planar. However, the two (P 4 )AgAl[OC(H)(CF 3 ) 2 ] 4 units in 3 dimerize by weak Ag À P contacts of 3.352(2) ± 3.429(2) ä, and if one weak Ag À F interaction per Ag atom (3.250(3) and 3.282(3) ä) is included, the local coordination environment of the silver atoms is elongated octahedral (Figure 8).…”

“…Both are only moderately stable at -30°C in a CO atmosphere, while ~~S -P~( C O )~( S O~F )~ is thermally stable up to 117°C (22) (18) is remarkable for another reason. Both Ag(CO)B(OTeF,), (14) and Ag(CO),-B(OTeF,), (15) decompose with CO release below 25°C with formation of AgB(OTeF,), (14) and AgB(OTeF,),. All three noble metal carbonyl fluoroantimonates undergo a more complex decomposition, which leads eventually to the formation of the corresponding metals rather than to a clean cleavage of CO.
