Photoluminescent coordination polymers of d10 metals with 4,4′-dipyridylsulfide (dps)

Five luminescent coordination polymers [Ag2(dps)2](ClO4)2 · MeCN, [Ag2(dps)2(μ2-MeCN)(MeCN)](ClO4)2 · MeCN · H2O, [Zn(dps)(CH3COO)2, [Zn(dps)2(H2O)2](ClO4)2 · H2O and [Cu2I2(dps)2] (where dps  =  4,4′-dipyridylsulfide) were prepared. Compound [Ag2(dps)2](ClO4)2 exhibits pseudo-supramolecular isomerism with different Ag⋯Ag, π−π, Ag⋯S and unusual Ag⋯(μ2-MeCN) supramolecular interactions. Both blue luminescent zinc compounds self-assembled into 3D structures of different topologies with intriguing C-H⋯O, H⋯O, and N⋯H bonds. The Cu(I) compound is a yellow luminescent 2D-network polymer.
