Reactions of CuX (X = Br-, I- or CN-) with various types of 2,2?-dipyridylamine (dpa) derivatives have been performed via a hydrothermal-solvothermal method and the products have been structurally characterized by X-ray crystallography. Four ligands with different coordination motifs were employed in the reactions, including angular N,N,N?,N?-tetra(2-pyridyl)-2,6-pyridinediamine (tppda); linear N,N,N?,N?-tetra(2-pyridyl)-1,4-phenylenediamine (tppa) and N,N,N?,N?-tetra(2-pyridyl)biphenyl-4,4?-diamine (tpbpa); and star-shaped tris-[4-(2,2?-dipyridylamino)-phenyl]amine (tdpa), which yielded eight copper(i) complexes exhibiting different stoichiometries of Cu-dpa and variable coordination modes of dpa. The compound [Cu2(tppda) (mu-I)2]n (1) forms a one dimensional (1D) coordination polymer exclusively through double mu2-I bridges, which arranges to two dimensional (2D) metal-organic frameworks (MOFs) via the face-to-face pi…pi stacking interactions from pyridyl rings. The compound [Cu 6(tppa)(mu3-Br)6]n (2) forms a 2D network linked through multiple mu3-Br bridges. The compound [Cu2(tppa)(mu-CN)2]n (3) is also a 2D MOF containing 1D (CuCN)n chains. The compounds [Cu(tpbpa)Br]n (4) and [Cu4(tpbpa)2(mu-I)4]n (5) display two different 1D assemblies: a zig-zag chain for 4 and a linear structure for 5. The compound [Cu4(tpbpa)(mu-CN)4] n (6) shows a pseudo-4,82 topological net, while the compound [Cu8(tpbpa)(mu-CN)8]n· 2nH2O (7) exhibits a three-dimensional (3D) framework containing a …PM… double helical structure, although both of them contain (CuCN)n chains. The compound [Cu2(tdpa)(mu-I) 2]n (8) is a zig-zag chain based on the star-shaped molecule tpda, in which one of three dpa-arms is free of coordination to metal ions. All complexes exhibit luminescence in the solid state.
