title: Lewis-base-stabilized dichlorosilylene: a two-electron sigma-donor ligand.
abstract: The first structurally described cobalt(I) Lewis-base-stabilized silylene complex [Co(CO)(3){SiCl(2)(IPr)}(2)](+)[CoCl(3)(THF)](-) [1; IPr = 1,3-bis(2,6-diisopropylphenyl)imidazol-2-ylidene] was prepared by applying the two-electron sigma-donor ligand SiCl(2)(IPr) through coordination with Co(2)(CO)(8). The bonding situation between ligand SiCl(2)(IPr) and the cobalt(I) metal center in [Co(CO)(3){SiCl(2)(IPr)}(2)](+) of 1 was investigated by (1)H NMR and IR spectroscopy, single-crystal X-ray structural analysis, and density functional theoretical calculations.
