One of the first examples of a transition metal complex coordinated to a Keggin-type anion [AlW12O40](5-): [Cu(2,2'-bipy)(2)]{(AlW11WO40)-W-VI-O-V[Cu(2,2'-bipy)(2)](2)}center dot 2H(2)O, was prepared by the hydrothermal method. Crystal data: monoclinic, space group P2(1)/n, a=18.83(3), b=20.40(4), c=21.76(4) angstrom, beta=96.67(3)degrees, V=8304(2) angstrom(3), Z=4, D-c=3.229 Mg m(-3), F(000)=7280, T=293(2) K, mu(Mo-K alpha)=17.402 mm(-1), R-1=0.0459, wR(2)=0.0902, GOF=1.082. The title compound is discrete, with a Keggin unit [(AlW11WO40)-W-VI-O-V](6-) linked to two transition metal coordination cations [Cu(2,2'-bipy)(2)](2+) via two surface bridging O atoms of the Keggin unit [(AlW11WO40)-W-VI-O-V](6-), respectively. In addition, there are discrete Cu(3) coordination cations [Cu(2,2'-bipy)(2)](2+).
