The crystal structures of 2,3-bis-(thio-phen-2-yl)pyrido[2,3-<i>b</i>]pyrazine, C<sub>15</sub>H<sub>9</sub>N<sub>3</sub>S<sub>2</sub> (<b>1</b>), and 7-bromo-2,3-bis-(thio-phen-2-yl)pyrido[2,3-<i>b</i>]pyrazine, C<sub>15</sub>H<sub>8</sub>BrN<sub>3</sub>S<sub>2</sub> (<b>2</b>), are discussed. Both mol-ecules crystallize in space group <i>P</i>2<sub>1</sub>/<i>c</i>. In <b>1</b>, the thienyl rings are inclined to the mean plane of the pyrido-pyrazine moiety by 6.16 (7) and 86.66 (8)°, where as i ...[more]
