Chelated heteroatoms in polyoxometalates and the topological equivalence of {Coiii(en)} to type II cis-dioxometal centers. Synthesis and structure of [{Co(en)(μ-OH)2Co(en)}{PW10O37Co(en)}2]8− and [K⊂{Co(en)WO4}{WO(H2O)}(PW9O34)2]12−
Abstract
The first examples of polyoxometalate structures that incorporate embedded chelated heteroatoms point to new possibilities for stereochemical control of applications.
