Mediated effect of substitutes on the strength of both types of hydrogen bonds formed between HNgF (Ng = He, Ar, Kr) and HCCX (X = H, F, Cl, Br, I, At, and CH3)

► The three complexes of HArF and acetylene were found. ► The mediated effect of substitutes have been studied. ► An unmonotonic dependence of CH⋯F H-bond on the noble atomic number. ► These complexes are combined mainly with electrostatic interactions.
