| Popis: | In the title complex, [ZnCl2(C6H4N2Se)2], the ZnII center is tetracoordinated by a Cl2N2 donor set in a distorted tetrahedral geometry. Some of the distortion from the ideal tetrahedral geometry might be ascribed to two agostic Z...H interactions The two 2,1,3-benzoselenadiazole ligands are each essentially planar and form a dihedral angle of 35.06 (9)°. An interesting feature of the crystal packing is the observation of short intermolecular contacts between Se and Se, Se and N, and N and N atoms. These arise as a result of three-center bridging of adjacent molecules into chains along the b axis. The crystal structure is stablilized by π–π interactions [minimum centroid–centroid distance = 3.5694 (18) Å]. |
