Bis(2,1,3-benzoselenadiazole-κN)dichloridozinc(II)
Abstract:
In the title complex, [ZnCl(2)(C(6)H(4)N(2)Se)(2)], the Zn(II) center is tetra-coordinated by a Cl(2)N(2) 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 inter-actions [minimum centroid-centroid distance = 3.5694 (18) Å].
