Hydrothermal synthesis and characterization of an unprecedented η-type octamolybdate:: [{Ni(phen)2}2(Mo8O26)]

A new octamolybdate-supported transition metal complex [{Ni(phen)(2)}(2)(Mo8O26)] (1) has been hydrothermally synthesized and characterized by the elemental analyses, IR spectrum, XPS spectra, TG analysis and the single crystal X-ray diffraction. Compound I crystallizes in the monoclinic space group P2(1)/c, a = 10.446(2) Angstrom, b = 12.103(2) Angstrom, c = 21.956(4) Angstrom, beta = 97.81(3)degrees, V = 2750.0(10) Angstrom(3), and Z = 2. The single crystal X-ray diffraction analysis reveals that compound I is constructed from a novel unprecedented eta-type octamolybdate cluster linked to two {Ni(phen)(2)}(2) coordination complexes.
