Crystal structure of orthorhombic γ-CdC2O4 (sp.gr. Pmna, a = 7.3217(1), b = 6.0231(1), c = 9.2545(2) ?, V = 408.12(1) ?3, Z = 8, Dx = 3.262 Μg·m?3) was solved from the powder diffraction pattern. Each metal atom in the structure is co-ordinated by seven oxygen atoms which belong to five oxalate-ions. Crystal packing containing the noticeable cavities in the [101] and [001] directions is not close and essentially differs from the known disordered α- and ordered β-modifications of transition metal oxalates. This modification seems to be meta-stable. It was found that spontaneous γ→β phase transition takes place for the γ-CdC2O4 aged during 6 month in air. This transition may be accelerated via the heating of γ-CdC2O4 with excessive amounts of oxalic acid.
