3,3′-Ethylenebis(3,4-dihydro-6-chloro-2H-1,3-benzoxazine)

Augusto Rivera; Jicli José Rojas; Jaime Ríos-Motta; Michal Dušek; Karla Fejfarová

The asymmetric unit of the title compound, C18H18Cl2N2O2, contains one half of an independent molecule, the other half being generated via a centre of inversion at the molecular centroid. In the crystal structure, molecular chains are formed through non-classical C—H⋯ O hydrogen bonds between an axial H atom of the oxazine ring and the O atom of a neighbouring molecule.
