以1,3,5-苯三羧酸三甲酯为原料，在温和条件下（210℃，5h）水热合成了一种新的三羧酸铟In12O(OH)12({OH}4,{H2O}5)[btc]6·≈31H2O，称为MIL-96 （btc=1,3,5-苯三羧酸三甲酯或三羧酸三甲酯种），并用单晶x射线衍射技术对其进行了表征。MIL-96 （In）结构具有三维金属有机骨架，包含孤立的三核μ3-氧桥接铟簇和无限链的InO4(OH)2和InO2(OH)3（H2O）八面体，形成一个基于18元环的六边形网络。这两种类型的铟实体通过三聚体相互连接，三聚体通过μ2-羟基键以特定的-顺-顺-反-序列连接成波纹状的铟八面体链。MIL-96的三维框架显示出三种空腔（其中两种估计≈400Å3volumes），其中包裹着自由水分子。后一种物质在150°C加热时除去。
A new indium trimesate In12O(OH)12({OH}4,{H2O}5)[btc]6·≈31H2O, called MIL-96, (btc=1,3,5-benzenetricarboxylate or trimesate species) was hydrothermally synthesized under mild condition (210°C, 5h) 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 μ3-oxo-bridged indium clusters and infinite chains of InO4(OH)2and InO2(OH)3(H2O) 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 μ2-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≈400Å3volumes), in which are encapsulated free water molecules. The latter species are removed upon heating at 150°C.
