The title compound, [Sn(C~6~H~5~)~3~(C~6~H~4~NO~3~)], possesses an infinite chain structure. The SnO~2~C~3~ centre has distorted trigonal–bipyramidal geometry with the O atoms in the apical positions. A strong intermolecular N—H...O hydrogen bond results in the formation of double chains.
## Abstract 1‐Methyl‐3,6,8‐trinitro‐2‐quinolone **(1)** behaved as the dienophile in Diels‐Alder reactions with dienes. When cyclopentadiene was used, cycloadduct **4** was obtained, which was then aromatized on treatment with triethylamine. In the reaction of **1** with hydrazone of 2‐butenal, phe
