キノキサリン誘導体の結晶構造解析：分子配座と分子間相互作用の検討
This study reports the crystal structure of an acetamide compound bearing a methoxy-nitrophenyl substituent and a methyloxo-dihydroquinoxalinyl moiety. The quinoxaline bicyclic system exhibits slight puckering, with a dihedral angle of 2.07° between the two fused rings. The overall molecular geometry adopts an L-shaped arrangement, and intramolecular hydrogen bonding dictates the spatial orientation of the substituted phenyl ring. The amide nitrogen is found to be nearly planar. Crystal packing is primarily governed by C-H···O hydrogen bond networks and slipped π-stacking interactions between adjacent molecules.
The delivery route is not clearly identifiable from this paper. For hydrogen intake, inhalation is the most efficient route; inhalation, however, carries explosion risk (empirical LFL of 10%; high-concentration devices are not recommended).
