A new indium trimesate In{sub 12}O(OH){sub 12}({l_brace}OH{r_brace}{sub 4},{l_brace}H{sub 2}O{r_brace}{sub 5})[btc]{sub 6}.{approx}31H{sub 2}O, called MIL-96 (btc = 1,3,5-benzenetricarboxylate or trimesate species) was hydrothermally synthesized under mild condition (210 deg. C, 5 h) in the presence of trimethyl 1,3,5-benzenetricarboxylate in water and characterized by single-crystal X-ray diffraction technique. The MIL-96 (In) structure exhibits a three-dimensional metal-organic framework containing isolated trinuclear {mu} {sub 3}-oxo-bridged indium clusters and infinite chains of InO{sub 4}(OH){sub 2} and InO{sub 2}(OH){sub 3}(H{sub 2}O) octahedra generating a hexagonal network based on 18-membered ring. The two types of indium entities are connected to each other through the trimesate species which induce corrugated chains of indium octahedra, linked via {mu} {sub 2}-hydroxo bonds with the specific -cis-cis-trans- sequence. The 3D framework of MIL-96 reveals three kind of cavities (two of them have estimated {approx} 400 A{sup 3} volumes), in which are encapsulated free water molecules. The latter species are removed upon heating at 150 deg. C.
