Some interesting bimetallic isopropoxides of nickel(Ⅱ) with gallium(Ⅲ) and zirconium(Ⅳ), Ni[Ga(OPr~1)_4]_2 and Ni[Zr_2(OPr_1)_9]_2 have been synthesized by the interaction of NiCl_2·2Pr~1OH with K[Ga(OPr~1)_4],and K[Zr_2(OPr~1)_9] respectively, in 1:2 molar ratio. These bimetallic isopropoxides undergo facile alcohol interchange reactions with primary alcohols. However, reactions with tertiary alcohols result in the isolation of partially substituted derivatives with the compositions, Ni[Ga(OPr~1)(OBu~t)_3]_2 and Ni[Zr_2(OPr~1)_3(OBu~t)_6]_2. Characterisation of these derivatives has been made on the basis of elemental analyses, infrared, electronic spectral and magnetic susceptibility measurements. These studies suggest an octahedral geometry for nickel(Ⅱ) in the primary bimetallic alkoxides, while in the case of secondary and tertiary derivatives, an equilibrium is suggested between octahedral and tetrahedral forms.##属性不符
Some interesting bimetallic isopropoxides of nickel (Ⅱ) with gallium (Ⅲ) and zirconium (Ⅳ), Ni [Ga (OPr ~ 1) _4] _2 and Ni [Zr_2 (OPr_1) _9] _2 have been synthesized by the interaction of NiCl_2 · These bimetallic isopropoxides undergo facile alcohol interchange reactions with primary alcohols. However, reactions of 2Pr ~ 1OH with K [Ga (OPr ~ 1) _4] and K [Zr_2 with tertiary alcohol results in the isolation of partially substituted derivatives with the compositions of Ni [Ga (OPr ~ 1) (OBu ~ t) _3] _2 and Ni [Zr_2 (OPr ~ 1) _3 (OBu ~ t) _6] _2. Characterization of these derivatives has been made on the basis of elemental analyzes, infrared, electronic spectral and magnetic susceptibility measurements. These studies suggest an octahedral geometry for nickel (II) in the primary bimetallic alkoxides, while in the case of secondary and tertiary derivatives, an equilibrium is suggested between octahedral and tetrahedral forms. ## Property does not match
