Abstract

Reaction of BaII and CrIII,VI compounds with oxalates in water affords a salt of empirical formula {Ba6(H2O)17[Cr(ox)3]4}·7H2O (1), consistent with the expected 3BaII/2CrIII ratio; the triclinic structure is held together by unusual water and oxalate bridges, and compound 1 proved to be suitable for the synthesis of new salts with chiral cations and anions.
