Tetra­kis(μ-anthracene-9-carboxyl­ato)bis­[(anthracene-9-carboxyl­ato)(2,2′-bipyrid­yl)lanthanum(III)]

The title complex, [La(2)(C(15)H(9)O(2))(6)(C(10)H(8)N(2))(2)], has a centrosymmetric binuclear cage structure in which two La(III )atoms are both nine-coordinated and bridged by four anthracene-9-carboxyl­ate ligands, with an La⋯La separation of 4.0880 (4) Å. The remaining coordination sites are occupied by two N atoms of a 2,2′-bipyridine (bipy) and two O atoms of an anthracene-9-carboxyl­ate ligand. The six anthracene-9-carboxyl­ate groups coordinate each La(III )atom in three different ways. Adjacent discrete dinuclear units are arranged into a one-dimensional chain along the [111] direction by inter­molecular π–π stacking inter­actions, with a centroid–centroid separation of 3.704 (7) Å.
