1-Methyl-2,3-dihydro-1H-benzimidazole-2-selone.

ABSTRACT: The title compound C(8)H(8)N(2)Se, is the product of the reaction of 2-chloro-1-methyl-benzimidazole with sodium hydro-selenide. The mol-ecule is almost planar (r.m.s. deviation = 0.041?Å) owing to the presence of the long chain of conjugated bonds (Se=C-NMe-C=C-C=C-C=C-NH). The C=Se bond length [1.838?(2)?Å] corresponds well to those found in the close analogs and indicates its pronounced double-bond character. In the crystal, mol-ecules form helicoidal chains along the b axis by means of N-H?Se hydrogen bonds.
