Trimethyl isocyanurate and triethyl isocyanurate.


The crystal structures of trimethyl isocyanurate, C6H9N3O3, (1), and triethyl isocyanurate, C9H15N3O3, (2), contain topologically similar C--H...O hydrogen-bonded networks. In (1), there are two symmetry-independent molecules and each forms its own layer structure. In (2), two of the ethyl groups point one way with respect to the heterocyclic ring, while… (More)
