Abstract

The structures of three 1,2,6,8-tetrasubstituted imidazonaphthyridine derivatives, 1-diethylaminomethyl-6,8-dimethyl-2-(4-methylphenyl)imidazo[1,2-a] [1,8]naphthyridine, (VII), 1-diethylaminomethyl-2-(4-methoxyphenyl)-6,8-dimethylimidazo[1,2-a][1,8] naphthyridine) (VIII), and 2-(4-bromophenyl)-1-diethylaminomethyl-6,8-dimethylimidazo[1,2-a][1,8] naphthyridine, (IX), are reported. Two molecules related by a pseudo inversion centre are present in the asymmetric unit of (IX). Intramolecular C-H···N hydrogen bonds are observed in (VII) and (IX) whereas an intermolecular C-H···O hydrogen bond is present in (VIII).
