title: Poly[hexa-aqua-copper(II) [di-μ(3)-sulfato-disodiate(I)]].
abstract: The title compound, {[Cu(H(2)O)(6)][Na(2)(SO(4))(2)]}(n), has been prepared under mild hydro-thermal conditions and has been structurally characterized. It exhibits a structure in which the inorganic frameworks are three-dimensional, participating in extensive hydrogen bonding. Copper occupies a special position (). The Na atom is coordinated by five O atoms of four sulfates [Na-O distances are between 2.825 (3) and 2.983 (3) Å]. The four O atoms of the sulfate ligand are coordinated to four Na atoms, the sulfate ligands coordinating in a chelating/bridging tetra-dentate mode.
