“…In contrast to their previous work, this catalyst could be recycled up to ten times with only a slight leaching percentage in the first 6 cycles 122 . Furthermore, they presented a porous, noncatenated analogue (denoted as Mn III SO-MOF) of their first Jacobsen catalyst based Zn-MOF (entry 8, Table 5) .…”

Since the discovery of Metal Organic Frameworks (MOFs) in the early 1990, the amount of new structures has grown exponentially. A MOF typically consists of inorganic nodes that are connected by organic linkers to form crystalline, highly porous structures. MOFs have attracted a lot of attention lately, as the versatile design of such materials holds promises of interesting applications in various fields. In this review, we will focus on the use of MOFs as heterogeneous oxidation catalysts. MOFs are very promising candidates to replace homogeneous catalysts by sustainable and stable heterogeneous catalysts. The catalytic active function can be either the active metal sites of the MOF itself or can be introduced as an extra functionality in the linker, a dopant or a "ship-in-a-bottle" complex. As the pore size, pore shape and functionality of MOFs can be designed in numerous ways, shape selectivity and even chiral selectivity can be created. In this review, we will present an overview on the state of the art of the use of MOFs as a heterogeneous catalyst in liquid phase oxidation reactions.

Two new Mn(II) coordination polymers formed with molecular formula [Mn(H 2 O) 2 (HBTC)Á(H 2 O)] 1 and [Mn(H 2 O) 2 (4,4 0 bipy)(HBTC) 2 ]Á(H4,4 0 bipy) 2 2, where BTC = 1,2,4-benzenetricarboxylate and 4,4 0 bipy = 4,4 0 bipydine, have been synthesized via hydrothermal approach and characterized by single crystal X-ray diffraction techniques. 1 is composed of Mn-H 2 O-Mn 1D chains and further the chains are linked by HBTC ligands to form a 2D network in the ab plane; 2 is constructed by Mn-4,4 0 bipyMn 1D chains along the b direction with Mn 2? ions coordinated to H 2 BTC and water as terminal ligands to form a 2D network. We also prepared a third compound with the molecular formula of [Mn(H 2 O)(HBTC)Á(H 2 O)] which has been recently structurally reported elsewhere. The magnetic properties of the three compounds have been studied in detail under variable temperatures. InroductionAn increasing interest has taken place in crystal engineering of metal-organic frameworks (MOFs, sometimes known as coordination polymers) or clusters containing manganese (2?, 3? or 4?) cations that stem from their potential applications as molecular magnets [1-3], in biochemistry [4, 5] and homogeneous catalysis [6,7] due to its intriguing inherent nature and various oxidation states including 2?, 3?, 4?, 6? to 7?. In order to construct manganese-based molecular magnets, chemists tend to use short bridging ligands such as O 2-, (OH) -, N 3 -, (CN) -and (SCN) - [1-3, 8, 9] to link Mn cations since the short Mn-Mn contact benefits the magnetic exchange between adjacent metal atoms.From the point view of crystal engineering, the structures and properties of metal organic framework compounds are determined not only by the nature of the metal centers as nodes but also by the functional organic ligands as linkers. When multidentate chelating ligands are employed to link metal cations, their versatile coordination modes are able to build new structural topologies and so provide new compounds which lead to new properties.
