“…The structural studies of Nassimbeni have been particularly important in identifying the commonest types of interactions and provide a solid body of evidence for the hydrogen-bonding interactions with Werner-type coordination compounds [59][60][61][62][63][64][65]. Studies such as these relate directly to the "outer-sphere" complexes implicated in studies of substitution mechanisms, in which the incoming ligands are non-covalently associated with the starting complexes (A-type mechanisms) or intermediates (D-type mechanisms) [66,67]. Of particular importance are kinetic and thermodynamic studies, establishing both the nature and strength of the outer-sphere interactions between the oligopyridine complexes and halides and their relevance to the reaction chemistry of these species [68][69][70][71][72][73][74][75][76][77][78].…”

An analysis of the [M(bpy)3]n+ (bpy = 2,2′-bipyridine) complexes with halide counterions in the Cambridge Structural Database reveals a common structural motif in two thirds of the compounds. This interaction involves the formation of 12 short C–H…X contacts between halide ions lying within sheets of the cations and H-3 and H-3′ of six [M(bpy)3]n+ complex cations. A second motif, also involving 12 short contacts, but with H-6 and H-5, is identified between halide ions lying between sheets of the [M(bpy)3]n+ cations.
