Abstract

In the title compound, C18H14O8·2C6H18N3OP, one acid and two phospho­ramide mol­ecules are linked together by strong O—H⋯O 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—H⋯O inter­actions.
