 Abstract: The crystal structure of the organic–inorganic title salt, [Mn(C18H18N2O4)(H2O)2]ClO4, has been redetermined at 100 K. In contrast to the crystal structure determinations at room temperature [Akitsu et al. (2005[Akitsu, T., Takeuchi, Y. & Einaga, Y. (2005). Acta Cryst. C61, m324-m328.]). Acta Cryst. C61, m324–m328; Bermejo et al. (2007[Bermejo, M. R., Fernández, M. I., Gómez-Fórneas, E., González-Noya, A., Maneiro, M., Pedrido, R. & Rodríguez, M. (2007). Eur. J. Inorg. Chem. pp. 3789-3797.]). Eur. J. Inorg. Chem. pp. 3789–3797], positional disorder of the ethyl­ene bridge in the Schiff base ligand and the perchlorate anion is not observed at 100 K. The MnIII ion is six-coordinated with the tetra­dentate Schiff base chelate ligand N,N′-bis­(3-meth­oxy-2-oxybenzyl­idene)ethyl­enedi­amine occupying coordination sites in the equatorial plane and the aqua ligands residing in the two axial positions. The octa­hedral coordination sphere of the MnIII ion exhibits an axial elongation due to the Jahn–Teller effect, which is characteristic of a d4 high-spin electronic configuration.
