Popis:	A large manganese-doped polyoxotitanate nanocluster, Ti14MnO14(OH)2(OEt)28, has been synthesized under solvothermal conditions. Its structure is similar to previously reported Ti17O24(O i Pr)20, but lacks 5-fold coordinated Ti atoms which are potential binding sites for photosensitizer molecules. The Mn atom is located at the center of the Keggin structure with Ti-O bond length indicative of Mn 2+ , a conclusion confirmed by NEXAFS measurements. Solid-state band gap measurements of the complex show a significant decrease compared with undoped polyoxotitanate nanoclusters and anatase, indicating the potential of Mn-doping for visible light photocatalysis.
