A trinuclear cobalt–cerium complex: bis­(2,2′-bipyridine)-1κ(2) N,N′;3κ(2) N,N′-hexa-μ-methacrylato-1:2κ(6) O:O′;2:3κ(6) O:O′-nitrato-2κ(2) O,O′-2-cerium(III)-1,3-dicobalt(II)

In the title trinuclear cobalt-cerium complex, [CeCo(2)(C(4)H(5)O(2))(6)(NO(3))(C(10)H(8)N(2))(2)], the Ce(III) and each of the two Co(II) ions are bridged by three bidentate methacrylate ligands. The Ce(III) center is coordinated by six O atoms from six methacrylate ligands and two O atoms from the nitrate anion in a distorted square-anti­prismatic geometry. Each Co(II) ion is coordinated by three O atoms from three methacrylate ligands and two N atoms from a 2,2′-bipyridine ligand in a distorted trigonal-pyramidal geometry. In the crystal structure, π–π inter­actions between the aromatic rings [centroid–centroid distances of 3.816 (8) and 3.756 (8) Å] link the mol­ecules into chains propagated in [01[Image: see text]]. Weak inter­molecular C—H⋯O hydrogen bonds further stabilize the crystal packing.
