(kappa~1-O2CMe),Br2 undergoes oxidative addition to give N(CH2Ar~(Bu_2~t)O)3]-SbBr2,while Me3NO centre dot 2H2O yields the oxo and hydroxo complexes {[kappa~4-N(CH2Ar~(Bu_2~t)O)3]Sb(mu-O)}2,[kappa~4-N(CH2Ar~(Bu_2~t)O)3]Sb(OH)2,and{[kappa~4-N(CH2Ar~(Bu_2...
On reaction with zinc(II) salts HSALIMP gives two types of complexes, (a) [Zn(SALIMP)X]2·yH2O (X=NO3, y=0 (I); X=I, y=3 (II) and (b) [Zn(HSALIMP)Cl2]·H2O (III). HSALIMP reacts with nickel(II) bromide to form a mononuclear complex [Ni(HSALIMP)2Br2] (VIII),...
