## Refinement Hydrogen atoms were refined at idealized positions riding on the carbon atoms with C aromatic -H=0.95Å and C methyl -H=0.98Å and isotropic displacement parameters U iso (H) = 1.2U(C eq ) or 1.5U(-CH 3 ). All CH 3 hydrogen atoms were allowed to rotate but not to tip.
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. Correspon
