The title compound, 2 C 2 H 8 N + ÁC 12 H 8 O 4 2À , crystallizes as a salt in space group P2 1 /n, the anion being located on an inversion center. The dimethylammonium cations link neighboring carboxylate anions via two N + ÐHÁ Á ÁO hydrogen bonds [HÁ Á ÁO = 1.72 (3) and 1.84 (3) A Ê , NÁ Á ÁO = 2.
The title compound, (C~2~H~8~N)~2~(C~8~H~20~N)~2~[H~2~V~10~O~28~], contains two crystallographically independent centrosymmetric polyvanadate clusters, each with a composition [V~10~O~28~H~2~]^4−^, with the H atoms attached to μ~2~-O atoms. A variety of O—H...O and N—H...O hydrogen bonds generate a
