RESUMEN
In the title complex, {[Cu(C8H8NO3S)2(H2O)] x 2 H2O}n, the Cu(II) cation has a distorted square-pyramidal coordination environment consisting of five O atoms, one from a water molecule, one from an N-O group and the other three from the carboxylate groups of two 3-(2-pyridylsulfanyl)propionate N-oxide anions. The aqua[3-(2-pyridylsulfanyl)propionato N-oxide]copper(II) moieties are bridged by 3-(2-pyridylsulfanyl)propionate N-oxide anions to form an infinite three-dimensional coordination polymer with a zigzag chain structure. The crystal structure is stabilized by hydrogen bonds.

1-Hydroxybenzotriazole and 1-hydroxypyridine-2-thione were incorporated as ligands with the cluster Ru3(CO)10 (NCMe)2 to give [(mu-H)Ru3(CO)10(mu2-2,3-eta2-NNN(O)C6 H4)] and [(mu-H)Ru3(CO)9(mu2-eta1 : eta2-C5H4N(O)S)], respectively. Irradiation of these two new triruthenium metal clusters individually with 350 nm UV light in a phosphate buffer (pH 6.0) containing form I DNA resulted in single-strand cleavage. Cluster [(mu-H)Ru3(CO)10(mu2-2,3--eta2-NNN (O)C6H4)] was also found to bind to calf thymus DNA upon UV irradiation.
