catena -Poly[[[aqua[3-(2-pyridylsulfanyl)propionato N -oxide-κ O ^1^]copper(II)]-μ-[3-(2-pyridylsulfanyl)propionato N -oxide-κ^3^ O ^3^: O ^1^, O ^1'^] dihydrate]

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.
