Tetra-kis(μ-naphthalene-1-acetato-1:2κO:O')bis-(naphthalene-1-acetato)-1κO,O';2κO,O'-bis-(1,10-phenanthroline)-1κN,N';2κN,N'-europium(III)samarium(III).

ABSTRACT: In the title compound, [EuSm(C(12)H(9)O(2))(6)(C(12)H(8)N(2))(2)], the metal site is statistically occupied (50:50) by Eu and Sm atoms, forming a centrosymmetric complex. The metal site is nine-coordinate, in a distorted monocapped square-anti-prismatic coordination geometry. Mol-ecules are linked into three chains by C-H⋯π interactions and C-H⋯O hydrogen bonds. The combination of these chains generates a three-dimensional framework structure. One of the bridging naphthalene-1-ace-tate ligands was found to be disordered over two sites; the site occupancies for the naphthylmethyl group refined to 0.628 (14) and 0.372 (14).
