Trimethyl 3,3',3''-(benzene-1,3,5-triyl)tripropynoate

<p>In the crystal of trimethyl 3,3',3''-(benzene-triyl)tripropynoate, a system of new hydrogen bond ring motifs involving C-H...O interactions give rise to layer formation of molecules while the layers are connected among each other via weak contacts of C---H...O and C---H...pi type to specifically complete the supramolecular packing structure.</p>
