Distrontium oxalate tetrahydroxidocuprate(II)
The crystal structure of distrontium oxalate tetra-hydroxidocuprate(II) or poly[tetra-μ-hydroxido-μ<sub>6</sub>-oxalato-copperdistrontium], Sr<sub>2</sub>(C<sub>2</sub>O<sub>4</sub>)[Cu(OH)<sub>4</sub>] or [Sr<sub>2</sub>Cu(C<sub>2</sub>O<sub>4</sub>)(OH)<sub>4</sub>] <sub><i>n</i></sub> , has been determined in the triclinic space group <i>P</i>1. The asymmetric unit contains one Sr, one Cu, two hydroxide groups, and half of an oxalate anion. By application of inversion symmetry, a square-planar {Cu(OH)<sub>4</sub>} unit and a complete oxalate anion are generated. The structure consists of a three-dimensional framework of edge-sharing {SrO<sub>4</sub>(OH)<sub>4</sub>} polyhedra decorated by {Cu(OH)<sub>4</sub>} units and oxalate groups. Only weak hydrogen bonds are observed within the framework.
