Abstract

In the polymeric title complex, {[Cu(C8H5NO4S)(H2O)]·3H2O}n, the CuII cation is coordinated by one water mol­ecule and four carboxyl­ate O atoms from four 2-[(carb­oxy­meth­yl)sulfan­yl]nicotinate anions in a distorted square-pyramidal geometry. The 2-[(carb­oxy­meth­yl)sulfan­yl]nicotinate anion bridges four CuII cations, forming a two-dimensional polymeric complex parallel to the bc plane. In the crystal, O—H⋯O, O—H⋯N and O—H⋯S hydrogen bonds link the complex mol­ecules and lattice water mol­ecules into a three-dimensional supra­molecular architecture.

The 2-[(carboxymethyl)sulfanyl]nicotinate anion bridges four CuII cations, forming a two-dimensional polymeric complex parallel to the bc plane. H O, O—H N and O—H S hydrogen bonds link the complex molecules and lattice water molecules into a threedimensional supramolecular architecture
