Four new heteropolyanions {[PMo 12 Sb 2 O 40 ][Cu(Im) 2 ] 2 } · Im ( 1 ), {[PMo 12 Sb 2 O 40 ][(Cd(Phen) 2 ) 2 Cl]} ( 2 ), [Cu(Phen) 2 ] 2 [PMo 12 Sb 2 O 40 ] ( 3 ) and [Cd(bpy) 4 (H 2 O) 2 ][PMo 12 Sb 2 O 40 ] · bpy · 2H 2 O ( 4 ) (Im = imidazole, Phen = 1,10‐phenanthroline, bpy = 4,4′‐bipyridine) have been synthesized and characterized by IR, UV/Vis spectrophotometry, X‐ray photoelectron spectroscopy, powder XRD analyses and elemental analyses. Single‐crystal X‐ray diffraction analyses revealed that these four compounds represent examples of compounds based on the bis‐antimony‐capped Keggin polyoxoanion {PMo 12 Sb 2 O 40 } and different transition‐metal coordination complexes. Compound 1 exhibits a novel 1D chain structure, compound 2 is the first example of an extended structure constructed from polyoxoanions, transition‐metal coordination complexes and halide ions and compounds 3 and 4 are supramolecular structures constructed from {PMo 12 Sb 2 O 40 } polyoxoanions and different transition‐metal coordination fragments.
