p-Arsanilic acid stabilizing titanium-oxo clusters with various core structures and light absorption behaviours

p-Arsanilic acid stabilizing titanium-oxo clusters with various core structures and light absorption behaviours
A series of p-arsanilic acid stabilizing polyoxo‑titanium clusters (PTCs) have been successfully synthesized through solvothermal method, which present {Ti4}, {Ti5} and {Ti6} cores functionalized by different carboxylic acid ligands. PTC-111 displays a {Ti4} core structure which is stabilized by glycolic acid and esterified p-arsanilic acid. PTC-112, PTC-113 and PTC-114 have isostructural {Ti6} structures, functionalized by isonicotinic acid, 2-chloroisonicotinic acid and benzoic acid, respectively. The {Ti5} core of PTC-115 is functionalized by m-nitrobenzoic acid. It is interesting that the light absorption behaviours of these PTCs are dependent on their core structures and the functionalizing ligands.
