The reactions of the Keplerate super cluster [Mo132O372(CH3CO2)(30)(H2O)(72)](42) with a Cu(II) source and an organonitrogen donor in methanol/DMF solutions yielded a series of bimetallic organic-inorganic oxide hybrid materials, including the molecular species [Cu(phen)(2)MoO4] (1) and [{Cu(terpy)}(2)(MoO4)(2)] (2) and a series of materials constructed from the tetranuclear building block {Mo4O10(OMe)(6)}(2) : the molecular [{Cu-2(phen)(2)(O2CCH3)(2) (MeOH)} Mo4O10(OMe)(6)] (3), [{Cu(terpy)(O2CCH3)}(2)Mo4O10(OMe)(6)] (4) and [{Cu(terpy)Cl}(2)Mo4O10(OMe)(6)] (5), the one-dimensional phases [{Cu(bpy)(HOMe)(2)}Mo4O10(OMe)(6)] (6), [{Cu(bpy)(DMF)(2)}Mo4O10(OMe)(6)] (7), [{Cu(bpa)(DMF)(2)}Mo4O10(OMe)(6)] (8), [{Cu(phen)(DMF)(2)}Mo4O10-(OMe)(6)] (9) and [{CuCl(dpa)}(2)Mo4O10(OMe)(6)] (10), and the two-dimensional material [{Cu-2(DMF)(2)(pd-pa)}{Mo4O10(OMe)(6)}(2)] (11). When methanol is replaced by the tridentate alkoxide tris-methoxypropane (trisp), the {Mo2O4(trisp)(2)}(2) cluster building block is observed for [Cu(phen)Mo2O4(trisp)(2)] (12), [Cu(bpa) (DMF)Mo2O4(trisp)(2)] (13) and [{Cu(bpy)(NO3)}(2)Mo2O4(trisp)(2)] (14).
