Di-μ-acetato-κO,O':O;κO:O,O'-bis-[(acetato-κO,O')(1,10-phenan-throline-κN,N')cadmium(II)].

The title compound, [Cd(2)(C(2)H(3)O(2))(4)(C(12)H(8)N(2))(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 π-π inter-action between stacked phen groups [centroid-centroid distance 3.5209 (11) Å], leading to a planar structure parallel to (010).
