title: 3,3'-Ethyl-enebis(3,4-dihydro-6-chloro-2H-1,3-benzoxazine).
abstract: The asymmetric unit of the title compound, C(18)H(18)Cl(2)N(2)O(2), contains one half of an independent mol-ecule, the other half being generated via a centre of inversion at the mol-ecular centroid. In the crystal structure, mol-ecular 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 mol-ecule.
