The title compound, [Cd2(C2H3O2)4(C12H8N2)2], consists of dimeric units built up around a crystallographic symmetry centre. Each cadmium(II) unit is chelated by a 1,10-phenanthroline (phen) group and two acetate ligands, one of which also acts as a bridge, linking both seven-coordinated cadmium(II) centres. The crystal structure is governed by a single [pi]-[pi] interaction between stacked phen groups [centroid-centroid distance 3.5209 (11) Å], leading to a planar structure parallel to (010).
