[Ni:1].CO.[C:4]([CH:8]1[C:15](C(C)(C)C)(O)[CH:14]=[CH:13][C:10]([CH2:11][OH:12])=[CH:9]1)(C)(C)[CH3:5].CC(O)C>C1C=CC=CC=1>[Ni:1].[CH3:11][OH:12].[CH3:5][CH2:4][CH2:8][CH2:9][CH2:10][CH2:13][CH2:14][CH3:15][2,2'-thiobis-(4-t-octylphenolato)]-2-propanol nickel II (83.9 g) prepared as described in Example 4 was dissolved in benzene (250 ml) and 3,4-di-t-butyl-4-hydroxybenzyl alcohol (35.5 g) was added. The temperature of the mixture was raised to reflux and the resulting solution was refluxed for 2.25 hr. Displaced 2-propanol and benzene (150 ml) were then distilled from the reaction mixture. Remaining solvent was removed by rotary evaporation. From the residue the complex [2,2'-thiobis-(4-t-octylphenolato)]-3,4-di-t-butyl-4-hydroxybenzyl alcohol nickel II was obtained by recrystallization from n-octane as a green solid m.p. 253°-255° C.
