Abstract
The structure of bis(2-pyridine-N-oxide) diselenide was determined by single crystal X-ray diffraction. The compound crystallized in the triclinic system and the structure was solved in the space group\(P\bar 1\). The lattice constants were determined to bea=7.174(2),b=7.176(2),c=11.070(2) Å, α=87.67(2)°, β=73.68(2)°, and γ=89.57(2)°;Z=2,D x=1.906 Mg m−3. The final least squares refinement based on 1942 independent observed reflections yieldedR=0.033,wR=0.044. The Se−Se′ bond length is 2.326(1) Å and each Se is coordinated to the O atom of the corresponding N-oxide moiety at a distance of about 2.6 Å.
