The molecular structure of the nickel formate compound, Ni(py)4(O2CH)2·2py, has been determined by X-ray diffraction, thereby demonstrating that the formate ligand coordinates in a unidentate manner. A similar investigation of the nitrate compound, Ni(py)4(ONO2)2·2py, indicates that the nitrate ligand also coordinates in a unidentate manner; however, the Ni–O–NO2 bond angle is distinctly bent, in...
The terminal zinc hydride complex, [TpBut,Me]ZnH, can be conveniently obtained from the hydroxide derivative, [TpBut,Me]ZnOH, by reaction with H3NBH3. The zinc hydride complex [TpBut,Me]ZnH is reactive and the Zn–H bond undergoes (i) insertion of CO2 to produce the formate complex, [TpBut,Me]Zn(κ1–O2CH), (ii) protolytic cleavage with Me3SiOH to afford [TpBut,Me]ZnOSiMe3, and (iii) metathesis with...
