Two new hybrid compounds based on polyoxometaloborates, (HIm) 12 [MnBW 11 O 39 H] 2 · 13H 2 O ( 1 ) and (HIm)(Im)[(Im) 4 Zn] 2 [BW 12 O 40 ] · 2H 2 O ( 2 ) (Im = imidazole), have been synthesized and characterized by elemental analyses, IR, UV, TG, and single‐crystal X‐ray diffraction. Compound 1 is made up of [MnBW 11 O 39 H] 6– polyoxoanions, which are coordinatively linked together by terminal oxygen atoms to yield an unprecedented one‐dimensional chain that represents the first example of one‐dimensional assemblies based on polyoxotungstoborates and transition metal cations. Adjacent inorganic chains are further in close contact by imidazole molecules to form a three‐dimensional supramolecular channel framework by strong hydrogen‐bonding interactions. Compound 2 exhibits a three‐dimensional supramolecular architecture constructed from Keggin‐type polyoxoanions [BW 12 O 40 ] 5– and zinc‐imidazole coordination units by strong hydrogen‐bonding interactions. Furthermore, both compounds exhibit interesting photoluminescence properties at room temperature.
