In the title compound, C24H20P+·C2HO4−, two symmetry-independent ion pairs are present.The cations aggregate into puckered sheets via zigzag infinite chains of sixfold phenyl embraces and parallel fourfold Straws phenyl embraces, while the anions form hydrogen-bonded chains between the sheets of cations.In the two independent oxalate anions, the angles between the normals to the two least-squares carboxylate COO planes Solar lighting kits are unusually large, viz.72.
