The title compound, C 14 H 13 NO 5 , exhibits a resonance-assisted hydrogen bond O-HÁ Á ÁO C [2.505 (4) A ˚], which leads to a lengthening of the carbonyl C O bond, a shortening of the C-OH bond and delocalization of the electron density within the dihydropyridine ring.

In the title compound, C~4~H~12~N^+^·C~11~H~12~Cl~2~O~6~P^−^·C~3~H~6~O, all bond lengths and angles are normal. Three ammonium H atoms participate in N—H...O hydrogen bonds, which stabilize the crystal packing along with weak intermolecular C—H...O interactions.
In the title racemic compound, C 9 H 19 O 5 P, all interatomic C-C and C-OH distances can be considered normal. The P-O and P O distances are 1.5583 (8) and 1.5003 (7) A ˚, respectively. The rings are cis-fused, the phospholane ring exists in a slightly distorted envelope conformation and the cycloh
