title: The Weakness of B-H⋅⋅⋅π Interactions: Much Softer than a Hydrogen Bond.
abstract: Recently, a new type of non-covalent interaction, the B-H⋅⋅⋅π interaction, was introduced. Nevertheless, the unique determination of individual, non-covalent bond strengths in complex molecular systems is a non-trivial task with often controversial results. The utilization of generalized compliance constants (relaxed force constants) is proposed as unique bond-strength descriptors for classical and non-classical hydrogen bonds. The strength of recently proposed B-H⋅⋅⋅π bonds is discussed.
