Metal–nucleobase interactions: Interplay of coordination and hydrogen bonding in cadmium (II) complexes of N6-substituted adenines

The X-ray crystal structures of 1 [Cd2(BAD+)2(μ-Cl)4Cl2]n (BAD+ = N3 protonated N6-benzyladenine)] and 2 [Cd2(FAD+)2(μ-Cl)4Cl2]n (FAD+ = N3 protonated N6-furfuryladenine) reveal an one-dimensional polymer. In both the structures, the interplay of coordination and hydrogen bonding results in the formation of almost the same type of supramolecular architectures via N–H⋯Cl, C–H⋯Cl and C–H⋯N hydrogen bonds.
