Two novel hexanuclear copper(II)-substituted tungstogermanates [Cu(2,2'-bipy)](2)[Cu(2,2'-bipy)(2)](2)[Cu(6)(2,2'-bipy)(2)(GeW(9)O(34))(2)]center dot 3H(2)O (1) (2,2'-bipy = 2,2'-bipyridine) and (Cuphen)(2)[Cu(phen)(2)](2) [Cu(6)phen(2) (GeW(9)O(34))(2)]center dot 2H(2)O (2) (phen = 1,10-phenanthroline), which both consist of two trilacunary [B-alpha-GeW(9)O(34)](10)-Keggin units incorporating a unique Cu(6)O(14)N(2) cluster and bridged by four copper complexes have been hydrothermally synthesized. They represent unreported two examples of Cu(6)-containing tungstogermanates and further act as natural molecular units for the construction of interesting 3-D supramolecular frameworks.
