Abstract
The complete molecule of the title compound, C 8 H 8 N 4 Se 2 , is generated by a crystallographic twofold axis: the almost planar 1,2,3-selenadiazole ring and its symmetry-generated partner are annulated to a cyclodeca-1,3-diene ring. Their dihedral angle amounts to 88.4 (2)° and the conformation of the hexamethylene chain is mostly staggered ( gauche ) except for a near- anti arrangement in the middle.Keywords
