“…However, they are usually stable at the room temperature under certain conditions. Many investigations have been performed to study halogen fluorides, such as ClFO 3 [8], ClF 3 O [9][10][11][12][13][14][15][16][17], ClF 3 O 2 [18][19][20], and BrF 3 O [17,21]. The adducts of ClFO 2 , e.g., ClFO 2 BF 3 and ClFO 2 AsF 5 were also studied and found to exist in ionic structures ClO 2 + BF 4 − and ClO 2 + AsF 6 − , respectively [22].…”
