Crystal structures of the Lewis acid-base adducts {[(CH)N]Ti-}[MeB(CF)]·1.5CH; LB = (CH)PO (1), -F-CHCN (2).

The reaction of [(CH)N]Ti-CH with the Lewis acid B(CF), followed by addition of the Lewis bases (CH)PO and -F-CHCN led to the complex salts tris-(di-cyclo-hexyl-amido)(tri-phenyl-phosphine oxide)titanium methyl-tris(penta-fluoro-phen-yl)borate toluene sesquisolvate, [Ti(CHN)(CHOP)](CHFB)·1.5CH, (), and tris-(di-cyclo-hexyl-amido)(4-fluoro-benzo-nitrile)-titanium methyl-tris-(penta-fluoro-phen-yl)borate toluene sesquisolvate, [Ti(CHN)(CHFN)](CHFB)·1.5CH, (), both crystallizing with 1.
