Rearrangement of a Krebs-Type Polyoxometalate upon Coordination of N,O-Bis(bidentate) Ligands
Selective coordination of 2,3-pyzdc to the Krebs-type [{Ni(H2O)(3)}(2)(WO2)(2)(SbW9O33)(2)](10-) anion promotes a skeletal rearrangement that results in the [(2,3-pyzdc)(2){NaNi2(H2O)(4)Sb2W20O70}(2)](22-) (Ni-4) hybrid dimer showing a novel dinickel containing a 20-tungsto-2-antimonate(III) framework stabilized by N,O-bis(bidentate) bridging ligands. The solution stability and magnetism of Ni4 is discussed.
