Atomtransferreactions involve the net transfer of an atom and one or more electrons from a donor molecule to an acceptor [l]. Over the past two decades, metal-centeredoxygenatomtransferreactions have been intensively studied. Oxygenatomtransfer from M=O containing donor complexes to olefins, paraffins and other substrates has been achieved and a consistent mechanistic picture is beginning to

analyses demonstrated that the thermal expansion behavior is caused by double structural distortions involving [Mn(salen)]+ units incorporated into the zigzag layers. Thermal relaxations produce structural transformations resulting in positive thermal expansion for 2·H2O and negative thermal expansion for 3. In the case of 1·H2O, the relaxation does not occur and zero thermal expansion results in the plane
调节物理性能的能力对于开发用于多种应用的新材料具有吸引力。理解和控制复杂的网络结构(例如配位聚合物(CP))中的结构动力学尤其具有挑战性。我们报告了一系列二维CP [Mn(salen)] 2 [M(CN)4 ]· x H 2 O(M = Pt(1),PtI 2(2)和MnN(3))包含显示依赖成分的各向异性热膨胀特性的锯齿形氰基网络层。可变温度单晶X射线结构分析表明,热膨胀行为是由涉及[Mn(salen)] +并入锯齿形层的单元的双重结构变形引起的。热松弛产生结构转变,导致2·H 2 O的正热膨胀和3的负热膨胀。在1·H 2 O的情况下,在200到380 K之间的平面中不会出现松弛并且零热膨胀。本研究提出了一种新的策略,该策略基于协调网络中的结构变形来控制框架的热响应性。

Catalytic fate of structurally characterized manganese(<scp>iii</scp>)–salen complexes towards efficient transformation of primary amides to amines or nitriles using hydrosilane
A convenient and selective hydrosilylative transformation of chemically inert primary amides (26 examples) into the corresponding primary amines with key functional group tolerance has been developed by using simple well-defined O,N,N,O donor salen-based earth abundant manganese(III) complexes under mild conditions. On a slight modification of the reaction condition by adding the blocking agent secondary
Magnetic anisotropy and field-induced slow relaxation of magnetization were studied in dinuclear and trinuclear heterobimetallic CoIII⋯MnIII complexes.
