Abstract

Hydrothermal synthesis under basic conditions has given a new cluster compound, Ni7(OH)8(ox)3(pip)3 (ox = oxalate; pip = piperazine). This hybrid material comprises inorganic Ni7(OH)8 clusters, which have a vertex-shared dicubane structure. These units are held together in a 3-dimensional coordination network by organic bridging ligands. Magnetic susceptibility studies suggest a ferromagnetic coupling within the cluster and an antiferromagnetic interaction between neighbouring Ni7 units. At low temperatures the material appears to undergo a magnetic phase transition to an ordered antiferromagnetic state with TN = 17 K.
