Two-dimensional oxides constructed from octamolybdate clusters and Mn+/tetrapyridylpyrazine subunits (M = Co, Ni: n = 2; M = Cu: n = 1)

Hydrothermal methods have allowed the preparation of three two-dimensional materials constructed from octamolybdate clusters and secondary metal/tetra-2-pyridylpyrazine subunits. The δ-Mo8O264- cluster of [{Cu2(tpyprz)}2Mo8O26] is illustrated.
