Hexakis(μ-naphthalene-1-acetato)bis[(1,10-phenanthroline)praseodymium(III)]N,N-dimethylformamide solvate

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 PrIII ion is nine-coordinate and the naphthalene acetate (NNA) ligands coordinated to the PrIII 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—H⋯O and C—H⋯π hydrogen bonds and π–π 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.
