Vibrational spectra of the two hydrates of strontium oxalate

• IR and Raman spectra of SrC2O4⋅H2O and SrC2O4⋅2H2O were recorded and assigned.
• Assignments are discussed in comparison with the related calcium oxalates.
• SrC2O4⋅2H2O is isomorphous with CaC2O4⋅2H2O (weddellite).
• SrC2O4⋅H2O and CaC2O4⋅H2O (whewellite) are not isostructural but are strongly related.
• Structural peculiarities of these oxalates are considered in the discussion.

The infrared and Raman spectra of the two hydrates of strontium oxalate, SrC2O4⋅H2O and SrC2O4⋅2H2O, were recorded and discussed on the basis of their structural peculiarities and in comparison with the spectra of the related calcium oxalates and other previously investigated metallic oxalates.
