✦ Synopsis

The title structure (commonly known as 2,2 0 ,5,5 0 -tetraselenafulvalene or tetraselenafulvalene), C 6 H 4 Se 4 , contains two independent molecules, one of which is planar and centrosymmetric. The other molecule has a pronounced boat conformation and no imposed crystallographic symmetry. Corresponding bond lengths in the two molecules are similar. A few short intermolecular SeÁ Á ÁSe contacts are present.

## Abstract The reaction of 2,5‐dimethyl‐3,4‐diselenocyanato‐1__H__‐pyrrole by NaBH~4~ or NaOCH~3~ led to tetraselenide **7** in quantitative yield. Treatment of protected tetraselenide **8** with LiAlH~4~ afforded the aluminum complex intermediate that was converted into pyrrole‐annelated 1,3‐dise
