Crystal structure of 1,2-bis(6-bromo-3,4-dihydro-2H-benz[e][1,3]oxazin-3-yl)ethane : a brominecontaining bis-benzoxazine

The title benzoxazine molecule, C18H18Br2N2O2, was prepared by a Mannich-type reaction of 4-bromo­phenol with ethane-1,2-di­amine and formaldehyde. The title compound crystallizes in the monoclinic space group C2/c with 
The title benzoxazine molecule, C18H18Br2N2O2, was prepared by a Mannich-type reaction of 4-bromo­phenol with ethane-1,2-di­amine and formaldehyde. The title compound crystallizes in the monoclinic space group C2/c with a centre of inversion located at the mid-point of the C-C bond of the central CH2CH2 spacer. The oxazinic ring adopts a half-chair conformation. The structure is compared to those of other functionalized benzoxazines synthesized in our laboratory. In the crystal, weak C-H...Br and C-H...O hydrogen bonds stack the mol­ecules along the b-axis direction.
