1907 Chem. Abstr. 1 2537 There is no simple or normal hydroxyl group in these compounds because they will not add HX to form an aquo salt. Hence they should not be designated ‘hydroxy’ compounds, but may be designated ‘ol’ compounds, to signify that the hydroxyl group is in the complex radical.
1929 J. A. Wilson Chem. & Leather 29 Bjerrum succeeded in preparing an ol-compound with a nucleus containing 12 chromium atoms.
1931 Jrnl. Physical Chem. 35 46 With the conversion of hydroxo groups to ol groups to oxo groups there results increasing resistance to the action of acids.
1931 Jrnl. Physical Chem. 35 47 The authors hazard the guess that the oxolation of ol complexes would result in a loss of the reaction with neutral salts.
1962 J. R. Leach tr. A. A. Grinberg Introd. Chem. Complex Compounds ix. 283 An OH group which is bound to two central ions is designated by the term ‘ol’.
1974 D. Nicholls Inorg. Complexes iii. 26 This species with the hydroxo or ol bridges can react in the presence of added base.
2001 Colloids & Surfaces A. (Electronic ed.) 194 81/2 In very acidic medium, the effect of gel coloring should disappear due to the condensation of the ol-group and the formation of oxy-polymers.
