Abstract

In the title compound, C34H31N2O8PS, the intramolecular distances provide evidence for polarization of the molecular electronic structure. The molecules are linked into complex chains of rings by three independent C-H center dot center dot center dot O hydrogen bonds. The significance of this study lies in its finding that two of the four carbonyl O atoms play no role in the hydrogen bonding, despite the large excess of potential hydrogen-bond donors present.
