Dipotassium naphthalene-1,8-dicarboxylate-potassium bicarbonate.
The title substance, tripotassium naphthalene-1,8-dicarboxylate bicarbonate, 3K+.C12H6O4(2-).HCO3-, crystallized in the centrosymmetric space group Pbca. There is a single hydrogen bond. In it, the O and H atoms are ordered and OD...OA is 2.651 (3) A. There is a single significant intermolecular C-H...O interaction, with C...OA = 3.480 (5) A. Each potassium ion is coordinated by an irregular polyhedron of O atoms. These three polyhedra contain eight, eight and five members; each O atom is a member of at least two polyhedra. Structural comparisons are made with tetrapotassium naphthalene-1,4,5,8-tetracarboxylate hexahydrate.
