Abstract: The asymmetric unit of the title compound, [Pr₂(C₁₂H₉O₂)₆(C₁₂H₈N₂)₂]·C₃H₇NO, contains two independent half-complex molecules, together with two molecules of solvent; the complex molecules are centrosymmetric. Each Pr^III ion is nine-coordinate and the naphthalene acetate (NNA) ligands coordinated to the Pr^III ion have three types of coordination mode. One of the NNA ligands is disordered over two sites; the site occupancies refined to 0.565 (17) and 0.435 (17). Molecules are linked into three chains by C-HO and C-H hydrogen bonds and - stacking interactions [centroid-to-centroid distance 3.944(3) Å] parallel to the a-axis direction and the [011] plane, respectively, and the [011] and a-axis chains are linked into sheets parallel to the [011] plane.
