In the title complex, [Ca(C6H15NO3)2](C7H3N2O6)2, the Ca2+ ion is sandwiched between two triethanolamine ligands, each of them coordinating through all four potential donor sites. The coordination polyhedron is distorted cubic. The 3,5-dinitrobenzoate counter anions do not interact directly with the cation but are hydrogen bonded to the hydroxyl groups of the triethanolamine ligands.
