Abstract
The crystal structure of the title compound (3-pyridyl selenocyanate, C6H4N2Se) has been determined by X-ray analysis. As expected, the Se-C p bond of length 1.863 (8) angstrom has greater double-bond character than the Se-C(sp2) bond of length 1.929 (6) angstrom. The C3-Se-C7 bon d angle is 94.8 (3)-degrees and the torsion angle C2-C3-Se-C7 is 46.1 (6)-degrees. There are two short intermolecular contacts involving die Se and an N atom of two adjacent molecules [Se...N1 2.843 (7) and Se. ..N2 3.387 (6) angstrom], which, with the two atoms covalently bonded to Se, form an approximate square-planar geometry about die metal atom .
