Abstract

Four di-Cu(II)-substituted sandwich-type germanomolybdates, (H(2)en)(2)H(7){[Na(0.5)(H(2)O)(3.5)](2)[Cu(2)(β-Y-GeMo(9)O(33))(2)]}·6H(2)O (1), (H(2)en)(2)H{[Na(2.5)(H(2)O)(12)](2)[Cu(en)(2)][Cu(2)(β-Y-GeMo(9)O(33))(2)]}·8H(2)O (2), [Na(4)(H(2)O)(12)](2)H(4)[Cu(2)(β-Y-GeMo(9)O(33))(2)]}·11H(2)O (3) and [Cu(en)(2)](2)[Cu(en)(2)(H(2)O)](2){[Cu(en)(2)](2)[Cu(2)(β-Y-GeMo(9)O(33))(2)]}·8H(2)O (4) (en = ethylenediamine), have been prepared. It is interesting that 1-3 were obtained in the same aqueous solution reaction system but exhibited different structures: 1 displays a 0D structure, 2 shows an organic-inorganic 1D chain structure, while 3 displays a 2D network. 4 was synthesized under hydrothermal condition by the same reagents, which represents the first transition metal-sandwiched organic-inorganic 2D heteropolymolybdate.
