Abstract

Unexpected trends in the strengths of halogen-bond based adducts of CY(3)I (Y = F, Cl, Br, I) with two typical Lewis bases (chloride and trimethylamine) show that the halogen-bond donor strength (Lewis acidity) of a compound R-X is not necessarily increased with higher electronegativity of the (carbon-based) group R.
