“…Although salicylaldoxime [22] has been known as a metal-chelating agent since 1930, reports on the ligating properties of salicylaldoxime towards trivalent transition metal ions are rare. [23,24] Our approach of using oximes as ligands has yielded several interesting 3d metal complexes with the cores [M A (oxime) 3 M B ] nϩ , [24] [M III 3 (µ 3 -O)(µ 2 -OPh)] 6ϩ (M ϭ Ti, V, Cr, Mn, Fe and Co), [25,26] [M III 6 (µ 3 -O) 2 (µ 2 -OOCR) 2 ] 12ϩ (M ϭ V, Cr, Mn, Fe) [27] and [(M III A ) 2 (µ 3 -O) 2 (M III B ) 2 ] 8ϩ (M A ϭ M B ϭ Fe III ; [4] M A ϭ Cr III , M B ϭ Fe III ; [13] M A ϭ Cr III , M B ϭ Mn III ).…”

“…This relation of analytically important properties to particular and characteristic groupings is also shown by two copper reagents-namely, benzoinoxime (40), C8H6-CH(OH)--C(NOH)-CeH6, and salicylaldoxime (22), CeH4CH(NOH)-OH. The first reagent is specific for copper in ammoniacal solution, the latter furnishes a separation of copper in acetic acid solution; in both cases the organic copper compounds are suitable for direct weighing in either macro-or microanalytical procedures because of the high purity and definite composition of the precipitates.…”

“…Ephraim found that salicylaldoxime, XXI, is a selective precipitant for copper, with which it forms a y'ellow-green inner complex, XXIa. A gravimetric method has been based on this finding (19). His investigations of the behavior of derivatives of salicylaldoxime showed (20) that compounds XXII to XXV have the same precipitating action as XXI.…”
