Dipyridylamine has been coupled with phenyl groups to yield new organic ligands. During the course of one reaction a lithium salt of dipyridylamine was isolated as the product. These new compounds were characterized by single crystal X-ray diffraction, which reveals that π–π stacking interactions as well as hydrogen bonding permeate the isolated compounds in the solid state. BrPhDPA, compound 1, crystallizes in the monoclinic P21 space group with cell parameters a = 5.8291(1), b = 8.8504(2), c = 13.2341(3) Å and β = 91.928(1)°. 3-ThPh(DPA)2, compound 4, crystallizes in the orthorhombic C2/c space group with cell parameters a = 14.8033(7), b = 11.4124(4), c = 16.11780(7) Å and β = 115.911(3)°. Finally the lithium salt, [Li(HDPA)(H2O)2](H2DPA)(Cl)2(H2O), compound 5, crystallizes in the monoclinic Cmcm space group with cell parameters a = 14.043(3), b = 12.370(3) and c = 13.389(3) Å. Aromatic derivatives of dipyridylamine have been isolated and crystallographically characterized, showing π–π stacking and C–H···π interactions and an interesting Li+ coordination compound.
