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.

Slow decomposition of L-ascorbic acid, carried out under aerobic conditions and in the presence of cadmium ions, results in formation of a crystalline product that is highly insoluble in water. This compound has been identified as a cadmium oxalate polymeric species with formula Cd(C(2)O(4)).3H(2)O. The crystal structure of this compound is described. Relevant crystal data are the following: C(4)H(12)O(14)Cd(2), fw = 508.94; triclinic; space group P1 (No. 1); a = 6.010(1) A, b = 6.668(1) A, c = 8.498(1) A; alpha = 74.64(1) degrees, beta = 74.25(1) degrees, gamma = 80.91(1) degrees; V = 314.7(5) A(3); Z = 1.
