Binding of fluoroanions by a cationic cobalt(III) complex: Syntheses, characterization and single crystal X-ray structure determination of [Co(phen)2CO3]BF4 and [Co(phen)2CO3]PF6·3H2O

A Water‐Rich Cobalt(II) Compound: Hydrothermal Synthesis, Spectroscopic, Thermal, Crystal Structure Characterization and Antimicrobial Properties

“…Sharma and co‐workers have reported some extensive work on tris‐(phenanthroline)Co(III) cationic compounds such as [Co(phen) 3 ](IO 4 ) 3 ⋅ 2H 2 O, [Co(phen) 3 ](C 7 H 4 NSO 3 ) 3 ⋅ 8.5H 2 O, [Co‐(phen) 3 ](BF 4 ) 3 ⋅ H 2 O, [Co(phen) 3 ](PF 6 ) 3 ⋅ CH 3 COCH 3 , [Co(phen) 3 ]‐(dnp) 3 ⋅ 4H 2 O, [Co(phen) 3 ](Cl)[(CH 3 ) 3 C 6 H 2 SO 3 ] 2− ⋅ 11H 2 O, and [Co(phen) 3 ] 2 [Hg(SCN) 4 ] 3 ⋅ 3H 2 O behaving as anion receptors where (IO 4 ) − , (C 7 H 4 NSO 3 ) − , (BF 4 ) − , (PF 6 ) − , (dnp) − , ((CH 3 ) 3 C 6 H 2 SO 3 ) − and (SCN) − are periodate, o ‐benzosulfimide, tetrafluoroborate, hexafluorophosphate, 2,4‐dinitrophenolate, mesitylene sulphonate and thiocyanate respectively [1–6] . Apart from this, a lot of literature has been devoted to the [Co(phen) 2 (CO 3 )] + core which has garnered much interest in the context of anion recognition [11–22] . A very little attention has been paid towards Co(II) compounds in anion sensing, for instance; Geraghty and co‐workers studied the role of [Co(phen) 3 ](oda) ⋅ 14H 2 O and [Co(phen) 3 ](nda) ⋅ 11.5H 2 O (where odaH 2 and ndaH 2 are octanedioic and nonanedioic acids respectively), significant in inhibiting the growth of yeast C. albicans [23] .…”

Iron Fluoroanions and Their Clusters by Electrospray Ionization of a Fluorinating Ionic Liquid

“…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].…”
