Abstract

Crystal structures for the isomeric compounds benzyl-(2-chloro-6-methylpyrimidin-4-yl)amine (1), as its hemi-hydrate, and benzyl-(4-chloro-6-methylpyrimidin-2-yl)amine (2) have been determined. Conformational differences lead to multiple molecules, i.e. two and three, in their respective structures. Layers feature in each of the crystal structures and are stabilized by substantial hydrogen-bonding interactions. Compound (1) crystallizes as a hemi-hydrate in the triclinic space group P-1 with a = 8.667(5) Å, b = 11.421(7) Å, c = 12.954(8) Å, α = 78.330(10)°, β = 84.553(10)°, γ = 75.510(9)°, and Z = 4. Compound (2) crystallizes in the monoclinic space group P21/c with a = 10.740(3) Å, b = 21.487(6) Å, c = 14.914(4) Å, β = 95.014(5)°, and Z = 12.

Index Abstract

Substantial hydrogen-bonding interactions leading to layer structures feature in each of the crystal structures of the isomeric title compounds.
