title: A T-shaped selenenyl halide.
abstract: The title selenenyl halide complex, 3-iodo-2-phenyl-3H-3-selenaindazole, C(12)H(9)IN(2)Se, has an almost planar conformation and a nearly ideal T-shape for the Se(INC) moiety [Se-I 2.8122 (12), Se-C 1.881 (7) and Se-N2 2.051 (6) A; C-Se-N 79.6 (3), C-Se-I 96.8 (2) and N-Se-I 176.17 (17) degrees ]. This arrangement, together with the two selenium lone pairs, leads to a distorted trigonal-bipyrimidal geometry about the Se atom. Intermolecular interactions are largely limited to stacking forces.
