Synthesis and the crystal and molecular structures of (H3 L • Cl)[CoCl4] and H2 L[CuBr4] (L is 2,4,6-Tri(N,N-dimethylamino)methylphenol)

The complex compounds (H3 L • Cl)[CoCl4] (I) and H2 L[CuBr4] (II), where L is 2,4,6-tri(N,N-dimethylamino) methylphenol, were isolated in the crystalline state and studied by X-ray diffraction. The organic cations were found to be outer-sphere ligands. All three nitrogen atoms of the tertiary amino groups are protonated. In compound I, the H3 L 3+ cation exists as the cis tautomer. In compound II, the H2 L 2+ dication exists as the trans isomer. In the crystal structure, the dications are arranged in layers via hydrogen bonds. © 2010 Pleiades Publishing, Ltd.
