Abstract

Symmetric tetrahedral ligands are prominent, but somewhat under-investigated building blocks for the generation of coordination polymeric networks. Coordination networks [Mn5Cl2(L1)2(H2O)4(DMF)4]·3H2O·7DMF, 1 and the [La2(H5L2)2(H2O)6], 2 are synthesized under mild solvothermal methods in DMF from the adamantane-based tetrahedral ligands, 1,3,5,7-tetrakis(4-phenyltetrazol-5-yl)adamantane (H4L1), reported for the first time, and 1,3,5,7-tetrakis(4-phenylphosphonic acid)adamantane (H8L2), respectively. Compounds 1 and 2 are based on completely different pentanuclear and binuclear secondary metal building units, respectively, and have different symmetries, but demonstrate an interesting coincidence of underlying topologies, which could be interpreted as a directing or ‘imprinting’ effect of the symmetry of the rigid tetrahedral ligands. Both structures represent examples of a rarely observed (4,8)-coordinated net. The χMT product for 1 at room temperature is slightly lower than the expected for five Mn(II) ions with S = 5/2 and g ≈ 1.98 and on lowering the temperature χMT approaches the expected value for a single Mn(II) as a result of the antiferromagnetic coupling through the tetrazolate bridges.
