摘要

A unique penta-coordinate nickel complex [{1,2-C ₆ H ₄ (SiMe ₂ )(SiH)} ₂ Ni(PEt ₃ )(depe)] (6) that generates two new Si-Si single bonds has been prepared exclusively by the reaction of a chelating silyl hydride 1-(dimethylsilyl)-2-silylbenzene (4) and Ni(depe)(PEt ₃ ) ₂ (depe = Et ₂ PCH ₂ CH ₂ PEt ₂ ) in a 2:1 ratio. Complex 6 is the first example of mononuclear silyl nickel complexes containing a Si-Si single bond formed in situ. Interestingly, framework 6 exhibits reversible single-crystal-to-single-crystal transformations upon the removal and rebinding of the coordinating PEt ₃ molecule, which give rise to a PEt ₃ -free complex [{1,2-C ₆ H ₄ (SiMe ₂ )(SiH)} ₂ Ni(depe)] (6′), concomitant with the alteration of the coordination geometry of central metal atoms.
