title: A trinuclear cobalt-cerium complex: bis-(2,2'-bipyridine)-1κN,N';3κN,N'-hexa-μ-methacrylato-1:2κO:O';2:3κO:O'-nitrato-2κO,O'-2-cerium(III)-1,3-dicobalt(II).
abstract: 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-anti-prismatic 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 inter-actions between the aromatic rings [centroid-centroid distances of 3.816 (8) and 3.756 (8) Å] link the mol-ecules into chains propagated in [01]. Weak inter-molecular C-H⋯O hydrogen bonds further stabilize the crystal packing.
