(1R,2R)-N,N'-Dimethyl-cyclo-hexane-1,2-diamine.

The molecule of the title compound, C(8)H(18)N(2), possesses C(2) symmetry. Owing to its stereochemistry, it is used in the synthesis of chiral ligands and metal complexes for asymmetric synthesis. The cyclo-hexane ring shows a chair conformation with the amino groups in equatorial positions. Contrary to the literature, the title compound is not a liquid, but a crystalline solid at room temperature (293 K). The absolute configuration is assigned from the synthesis.
