Silylene complexes from a stable silylene and metal carbonyls: synthesis and structure of [Ni{(ButN–CHCH–NBut)Si}2(CO)2], a donor-free bis-silylene complex

Abstract

[Ni(LSi)₂(CO)₂]3; the first silylene complex of nickel, has been obtained from the stable silylene 1,3-di-tert-2,3-dihydro-1H-1,3,2-diazasilol-2-ylidene (LSi)1 and tetracarbonylnickel; complex 3 was characterized by single crystal X-ray diffraction and NMR spectroscopy (¹H, ¹³C, ²⁹Si).
