Modification of the borane moiety in 2Ni was explored by the treatment of this complex with 4-dimethylaminopyridine (DMAP) to produce [PhB(DMAP)(CH2PtBu2)2]NiCl (4), which displays distinct features in its UV–visible spectrum compared to 2Ni. The solid-state molecular structures of most complexes have been determined
