摘要

锰配合物的化学性质因其不同的氧化值和不同的核性质而受到许多研究者的关注,与锰酶活性中心的模型配合物有关,如Mn SOD(超氧化物歧化酶)、Mn过氧化氢酶和光系统II中的Mn4CaO5簇。1 - 3六氟硅酸锰可以作为制造锰配合物的金属来源之一。然而,这种金属源的晶体结构至今尚未公开。据我们所知,在有关简单锰盐晶体结构的文献中,意外地只出现了一篇关于三酸锰的报道在本研究中,我们确定了六水六氟硅酸锰(II)的晶体结构,其晶体结构为一个八面体六氟硅酸锰离子与一个八面体六氟硅酸锰离子,如图1所示。本文描述了[Mn(H2O)6]SiF6(1)的晶体结构和磁化率对温度的依赖关系。将六水六氟硅酸锰(II)从蒸馏水中重结晶,得到淡粉色晶体。IR (cm-1): ν(OH) 3400 (br), δ(H2O) 1624 (s), ν(SiF) 743 (s), 469 (s)。进行了初步检验,数据收集于2020©The Japan Society for Analytical Chemistry

Crystal Structure and Magnetic Property of Manganese(II) Hexafluorosilicate Hexahydrate
The chemistry of manganese complexes has attracted much attention of many researchers because of the various oxidation numbers and diverse nuclearities, having relevance to model complexes of active centers in manganese enzymes, such as Mn SOD (superoxide dismutase), Mn catalase, and Mn4CaO5 cluster in Photosystem II.1–3 Manganese(II) hexafluorosilicate may be useful as one of the metal source to make manganese complexes. However, the crystal structure of this metal source has not yet been disclosed so far. To our knowledge, unexpectedly only one report concerning manganese(II) triflate has appeared in the literature concerning crystal structures of simple manganese(II) salts.4 In this study, we determined the crystal structure of manganese(II) hexafluorosilicate hexahydrate, which shows an octahedral hexaaquamanganese(II) ion with an octahedral hexafluorosilicate ion, as shown in Fig. 1. This paper describes the crystal structure and temperature dependence of the magnetic susceptibility of [Mn(H2O)6]SiF6 (1). Manganese(II) hexafluorosilicate hexahydrate was recrystallized from distilled water to give pale-pink crystals. IR (cm–1): ν(OH) 3400 (br), δ(H2O) 1624 (s), ν(SiF) 743 (s), 469 (s). A preliminary examination was made, and data were collected 2020 © The Japan Society for Analytical Chemistry
