Deskripsi
In the title trinuclear cobalt-cerium complex, [CeCo2(C4H5O2)6(NO3)(C10H8N2)2], the CeIII and each of the two CoII ions are bridged by three bidentate methacrylate ligands. The CeIII 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 CoII 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 [01overline{1}]. Weak intermolecular C—H...O hydrogen bonds further stabilize the crystal packing.
