✦ Synopsis

In the title compound, C 18 H 14 O 8 Á2C 6 H 18 N 3 OP, one acid and two phosphoramide molecules are linked together by strong O-HÁ Á ÁO hydrogen bonds. There are two crystallographically independent amide-acid assemblies in the asymmetric unit. Three of the four symmetry-independent phosphoramide molecules adopt propeller-like conformations. The crystal structure is additionally stabilized by C-HÁ Á ÁO interactions.
