The crystal and molecular structure of tris(tropolonato)scandium(III), Sc(C7H5O2)3, has been determined by a single-crystal X-ray diffraction technique. The compound crystallizes in the space group R3c, with cell constants a = 10.455 (2) and c = 32.595 (1) ? in the hexagonal setting. Least-squares refinement of the counter data gave a final R factor of 0.033 for 783 significant reflections. The complex has D3 imposed molecular symmetry. The coordination environment is intermediate between trigonal antiprismatic and trigonal prismatic as determined from a value of 33° for the projected twist angle Φ. The significance of Φ and its relationship to both metal ion and ligand restrictions is discussed.
