Fun, Hoong Kun published the artcile2,7-Bis(trichloromethyl)-1,8-naphthyridine, Category: naphthyridine, the publication is Acta Crystallographica, Section E: Structure Reports Online (2010), 66(3), o622, database is CAplus and MEDLINE.
The complete mol. of 2,7-bis(trichloromethyl)-1,8-naphthyridine, C10H4Cl6N2, is generated by crystallog. 2-fold symmetry, with 2 C atoms lying on the rotation axis; the 1,8-naphthyridine ring is almost planar with an root-mean-square deviation of 0.0002 Å. In the crystal structure, the mols. are stacked in an antiparallel manner along [001]. Short Cl···Cl [3.3502(4)] and Cl···N [3.2004(11)-3.2220(10) Å] contacts are observed in the crystal structure, as are π-π antistacking interactions. Crystallog. data are given.
