5-Chloro-2-methyl-sulfanyl-6-(naphtha-len-1-yl-oxy)-1H-benzimidazole methanol monosolvate.

In the title compound, C18H13ClN2OS·CH3OH, the dihedral angle between the benzimidazole group and the naphth-yloxy moiety [82.89 (5)°] very near to orthogonality. The H atom in the five-membered ring is disordered with equal occupancies at the two N atoms and the H atom of the methano-lic hy-droxy group is disordered with equal occupancies over two sites at the O atom. The methanol mol-ecule acts as a hydrogen-bond acceptor for the amino H atom and donates a hydrogen bond to the nonprotonated ring N atom. As a result, chains are formed running along the a axis.

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes.

Refinement. H1N H1O and H2N H2O disordered over two sites with occupancies 0.50:0.50
