First coordination polymer based on diterpenoids. Synthesis, structure, and magnetic properties

Resumo

One-dimensional coordination polymer was obtained by cation exchange reaction of triethylammonium salt of methyl ent-16α-H-phosphonyloxybeyeran-19-oate with CuCl₂. Its structure was determined by single crystal X-ray diffraction analysis. The formation of hydrophilic channels consisting of phosphorus containing fragments, copper atoms, and water, which are framed by hydrophobic surroundings from tetracyclic bulky beyeran substituents, is observed in the crystal. The study of the temperature dependence of the static magnetic susceptibility of the polymer indicates a weak antiferromagnetic interaction between the copper spins.
