Heteroatom control in the assembly of nanoscale gigantic heteropolyoxotungstates was accomplished by using SeO 3 2− to give [H 2 W 43 Se 3 O 148 ] 24− {W 43 Se 3 }, [H 4 W 77 Se 5 O 265 ] 44− {W 77 Se 5 }, [H 6 W 63 Se 6 O 221 ] 34− {W 63 Se 6 }, and [H 8 W 100 Se 16 O 364 ] 56− {W 101 Se 16 } cluster anions. The clusters are all derived from a common {W 22 Se 2 } building block and are constructed without the need to employ addition heterometallic linkers; the three smaller clusters incorporate pentagonal W(W 4 ) units.
