Synthesis,characterization, and catalytic activity of heterometallic ion-pair Ni/Mn and Ni/Zn complexes |
| |
| Abstract: | Two new heterometallic compounds, [Ni(bpy)3][Mn(NCO)4]·H2O (1) and [Ni(phen)3]2[Zn(NCO)4]2·4DMSO·H2O (2) [bpy?=?2,2′-bipyridine and phen?=?1,10-phenanthroline], have been synthesized and characterized. The structures of 1 and 2 were solved by single-crystal X-ray diffraction analysis. The cationic moieties of [Ni(bpy)3]2+ in 1 and [Ni(phen)3]2+ in 2 show octahedral environments around Ni(II), whereas the anionic groups of [Mn(NCO)4]2? in 1 and [Zn(NCO)4]2? in 2 exhibit tetrahedral geometry around the Mn(II) and Zn(II), respectively. Both compounds are catalysts in the H/D exchange of salicylaldehyde in DMSO-d6 which takes place under mild conditions and short reaction time. |
