N2 - Three new organic/inorganic coordination polymers, [{Cu(4-DPDS) 2(H2O)}·2NO3·3H 2O]n (1), [{Cu(4-DPDS)2(SO 4)}· 1.5H2O·CH3OH]n (2), and [Cd(4-DPDS)2Cl2]n (3), have been synthesized by using the flexible ligand 4,4′-dipyridyl disulfide (4-DPDS). Complex 1 crystallized in the Ibca space group: a = 10.5275(6), b = 20.2670(1), c = 27.235(1) Å, V = 5811.5(6) Å3, Z = 16. Complex 2 crystallized in the Pnna space group: a = 10.547(2), b = 14.201(2), c = 19.667(3) Å, V = 2945.8(8) Å3, Z = 8. Complex 3 crystallized in the P21/c space group: a = 7.6146(3), b = 18.2606(8), c = 9.3203(2) Å, β = 100.26(1)°, V = 1275.24(8) Å 3, Z = 4. The three coordination polymers display a variety of structural architectures, ranging from double-stranded chains (1) to two-dimensional channels (2) and two-dimensional, puckered, grid-like arrays (3). Magnetic characterizations show that complex 1 exhibits antiferromagnetic interactions while 2 is ferromagnetic. Solid-state fluorescence results reveal that 3 exhibits fluorescence emissions at 418 and 575 nm (λex = 314 nm).
