Abstract

There is essential stereochemical difference between the molecules of the monoclinic and triclinic polymorph of tris(1,3-diphenylpropane-1,3-dionato)-cobalt(III), C45H33CoO6. The monoclinic form crystallizes with the space group P21/c. The crystal data are: a = 17.257(4) Å, b = 9.951(2) Å, c = 20.786(5) Å, β = 92.73(2)°, V = 3565(1) Å3, Z = 4, λ(MoKα) = 0.7107 Å, μMoKα) = 0.53 mm−1, Dx = 1.358 g cm−3. The structure was solved by the heavy-atom method. The structure was refined by full-matrix least-squares technique with terminal phenyl rings taken as ideal hexagons to R = 0.050 for 3652 unique reflections. Only very weak intermolecular attraction forces keep the individual molecules together and the contacts between neighboring molecules correspond to the normal van der Waals interactions. The cobalt environment is a distorted octahedron with Co–O bond lengths ranging from 1.872(3) Å to 1.897(3) Å. The rotation of the terminal phenyl rings in relation to the chelate plane depends on the intramolecular steric hindrances and the tendency of the ligand to achieve planarity as a delocalized π-electron system.
