Three azide complexes with the tridentate ligand 2, 6-bis(benzimidazol-2- yl)pyridine (H2BBIP) were synthesized and their complicated supramolecular interactions were investigated with single-crystal X-ray diffraction. Interestingly, the complexes are assembled by bifurcated hydrogen bonding, double helical π-π stacking, or anion-π stacking interactions of the benzimidazole rings by tuning the reaction conditions (temperature, ratio, solvent). Complex 1 is a mononuclear compound, namely, Mn(H 2BBIP)N3(CH3O)·CH3OH. In its 3D supramolecular network, the nitrogen atom of the azide anion is acting as hydrogen bonding bifurcated acceptor. Complex 2 is a dinuclear compound, namely, Mn2(H2BBIP)2(N3) 2·(H2O)0.5. The dinuclear unit is connected by intramolecular π-π stacking interactions. Furthermore, double helical π-π stacking interactions in the benzimidazole rings are observed. Complex 3, Mn2(H2BBIP)2(N 3)2·CH3OH, can be formulated as a pseudopolymorph of complex 2, which exhibits intramolecular π-π stacking interactions as well as anion-π interactions in the dinuclear unit.
