Abstract
Crystals of the title compound (II) are monoclinic, space group P21/n, with a= 6.707(5), b= 9.978(6), c= 25.41(1)Å, β= 90.75(5)°. Except for the terminal methyl groups, the molecules are planar with non-crystallographic C2v(mm) symmetry. There are two types of Se–Se bond of length 2.45 and 2.80 Å. The structure was solved by a combination of direct and heavy-atom methods from 1 890 photographic data. It was refined by least-squares techniques to R 0.08.Keywords
