Monohydrides of the Group 13 Elements M=B, Al and Ga: Axial Bi-Nucleophilicity and the Propensity to Form Both H-M...HX and M-H...HX Hydrogen Bonds (X=F, Cl, Br, I, CN, CCH, CP)

Nucleophilicities NH−M of H−M (M=Al or Ga) when forming H-bond complexes with HX are the gradients. Both H and M ends of M−H are nucleophilic and can form H-bond complexes, with NH end>NM end . The order of NH−M is Ga ~Al when atom M is the H-bond acceptor and also Ga ~ Al when H is the acceptor.
