WebThe clusters [Ti 8 O 8 (OOCR) 16], consisting of an octameric oxo core surrounded by 16 carboxylate ligands, are obtained under solvothermal conditions inhigh yields. For the first time, the ability of these nanoobjects to be post-modified by other organic acids with the preservation of the octameric oxo core is demonstrated. WebTi−O−Ti or Ti−OR−Ti units also connect the Ti atoms, as in Ti x O y (OR) 4x−2y, while the organic ligands are bonded to the cluster surface. Bi- and multidentate capping ligands …
