The ability of alkylseleno/alkyltelluroacetylenes such as bis(selenomethylethynyl)-perfluorobenzene ( 4F-Se ) to act as a ditopic chalcogen bond (ChB) donor in co-crystals with ditopic Lewis bases such as 4,4'-bipyridine is extended here to the octafluorobiphenylene analog, 4,4'-bis(selenomethylethynyl)-perfluorobiphenyl ( 8F-Se ), with the more electron-rich 4,4'-bipyridylethane ( bpe ), showing in the 1:1 ( 8F-Se )•( bpe ) co-crystal a shorter and more linear C-Se•••N ChB interaction than in ( 4F-Se )•( bpe ), with Se•••N distances down to 2.958(2) Å at 150 K, i.e., a reduction ratio of 0.85 vs. the van der Waals contact distance.
