Abstract
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.
