Two novel mixed-valent manganese (Mn(II)/Mn(III)) cluster compounds were synthesized in solvothermal reactions and characterized by single-crystal X-ray diffraction, bond valence sum calculations, IR spectra, elemental analysis, and magnetic measurements. Compound 1 is a Mn 19 cluster with a cylindrical core structure. Compound 2 possess a Mn 16 core where all of the manganese sites have unique ligation
在溶剂热反应中合成了两种新型的混合价锰(Mn(II)/ Mn(III))簇化合物,并通过单晶X射线衍射,键合价和计算,IR光谱,元素分析和磁测量进行了表征。化合物1是具有圆柱形核结构的Mn 19簇。化合物2具有Mn 16核,其中所有锰位点均具有独特的连接环境。两种化合物的磁性测量结果表明金属中心之间主要的反铁磁相互作用。
