(1H-Imidazol-4-yl)methanol.

The title compound, C4H6N2O, displays two predominant hydrogen-bonding inter-actions in the crystal structure. The first is between the unprotonated imidazole N atom of one mol-ecule and the hy-droxy H atom of an adjacent mol-ecule. The second is between the hy-droxy O atom of one mol-ecule and the imidazole N-H group of a corresponding mol-ecule.

1,3-Bis(chloro-meth-yl)benzene.

The title compound, C8H8Cl2, used in the synthesis of many pharmaceutical inter-mediates, forms a three-dimensional network through chlorine-chlorine inter-actions in the solid-state that measure 3.513 (1) and 3.768 (3) Å.

1,6-Di-bromo-naphthalen-2-ol methanol monosolvate.

The naphthol-containing mol-ecule of the title compound, C10H6Br2O·CH3OH, crystallized as a methanol monosolvate and is planar to within 0.069 (1) Å for all non-H atoms. In the crystal, mol-ecules are linked by two pairs of O-H⋯O hydrogen bonds, involving the methanol mol-ecule, forming dimer-like arrangements.
