Abstract
In the title compound, poly[cobalt(II)-bis(μ-hydroxyacetato-O1,O2:O1′)], [Co(C2H3O3)2]n, units of [Co(C2H3O3)2] constitute a bidimensional sheet coordination polymer in which each CoII atom lies on an inversion centre and is octahedrally coordinated to glycolate ligands in a trans configuration. Carbonyl O atoms from adjacent units complete the octahedral environment.
