A methyl-ene group of one of the thf ligands is disordered over two orientations. In the crystal, a weak C-H⋯O inter-action generates inversion dimers. A Hirshfeld surface analysis shows that H⋯H contacts dominate the packing (86%) followed by O⋯H/H⋯O and C⋯H/H⋯C contacts, which contribute 3% and 10.4%, respectively.Acta crystallographica.
