Abstract
The crystal structures of the title compounds, [Ce(C5H7O2)(3)(C12H8N2) ], (1), and [Pr(C5H7O2)(3)(C12H8N2)], (2), have been determined. There are two independent molecules in the asymmetric unit of (1), but only one molecule in the asymmetric unit of (2). In both compounds, the me tal atom is eightfold coordinated by six O and two N atoms in a slight ly distorted square-antiprismatic arrangement. The ligands span the op posite edges of the two square faces of the coordination antiprism. Im portant bond-distance ranges are: Ce-O 2.434(7)-2.499(7), Ce-N 2.70(1) -2.767(9), Pr-O 2.392(5)-2.437(6) and Pr-N 2.659 (5)-2.690 (6) Angstro m.
