Amine-boranes are considered as to be promising materials for hydrogen storage systems due to their availability, easy handling and elevated hydrogen content. Formation of dihydrogen bonded adduct NH…HB that promotes H2 evolution for amine-boranes. Types of known mechanisms for NH and BH bonds activation by TM complexes for amine-boranes dehydrogenation will be consideration. Non-covalent interactions are the driving force in these processes. Particular attention will be paid intermolecular cooperative activation of amine-boranes. DHB between two transition metal hydrides results in H2 evolution and formation of bimetallic complexes [LM(CO)2(μ-CO)ڮM’(PCP)]. In these complexes two transition metal-based building units do not interact directly but act as a Lewis acid and a Lewis base, cooperatively splitting the N–H and B–H bond in amine-boranes without changing the metals' oxidation state. In the case of manganese(I) complexes the Lewis acid and base can be generated from one precursor - L2Mn(CO)3X. The intermolecular activation of amine-boranes is realised through novel cooperative action of [MnH] base and [Mn]+ Lewis acid yielding the record catalytic activity for BH3NHMe2 when L2 = bis(NHC).
