| Abstract: | The formation, crystal structure and properties of five copper(II) coordination compounds with the angular ligand, 4,4′-dipyridyl sulfide (dps) are described, {Cu3(μ-dps)4(μ-SO4)2(SO4)(H2O)5] · 10H2O}∞ (1 · 10H2O), Cu(dps)4(H2O)2] · (ClO4)2 · H2O (2 · H2O), {Cu(μ-dps)2(DMF)2](ClO4)2}∞ (3), {Cu(μ-dps)2(H2O)2] · (NO3)2 · 2H2O}∞ (4 · 2H2O) and {Cu3(μ-dps)6(DMF)2(H2O)4] · (NO3)6 · (DMF) · 6H2O}∞ (5 · DMF · 6H2O). The topological architectures of all these coordination compounds are strongly dependent on the counteranions, with the aid of guest solvents, and include a chiral 3D non-interpenetrated structure for 1, an acentric mononuclear structure for 2, acentric 2D undulating networks for 3 and 5, and a chiral 1D double-stranded chain for 4. In particular, all these acentric or chiral coordination architectures are generated from an achiral ligand as a building unit, and their second-order non-linear optical (NLO) properties are also studied in this paper. |
