Abstract

The title compound, [CdBr(CHN)] , was prepared by the reaction of cadmium bromide with 2,5-di-methyl-pyrazine in water. Its asymmetric unit consists of one Cd cation and one 2,5-di-methyl-pyrazine ligand that are located on a crystallographic mirror plane as well as one bromide anion that occupies a general position. The Cd cations are sixfold coordinated by four bromide anions and two 2,5-di-methyl-pyrazine ligands within slightly distorted -CdBrN octa-hedra. The cations are linked into [100] chains pairs of bridging bromide anions that are further connected into (001) layers by the bridging 2,5-di-methyl-pyrazine ligands. Powder X-ray diffraction (PXRD) shows that a pure crystalline phase has been obtained. Thermogravimetry coupled to differential thermoanalysis (TG-TDA) reveal that the 2,5-di-methyl-pyrazine ligands are removed in two separate steps leading to the formation of a compound with the composition (CdBr)(2,5-di-methyl-pyrazine) that decomposes into CdBr upon further heating. PXRD measurements of the residue obtained after the first mass loss show that a new crystalline phase has been formed.

摘要

标题化合物[CdBr(CHN)] 通过溴化镉与2,5 - 二甲基吡嗪在水中反应制备而成。其不对称单元由位于晶体学镜面的一个镉阳离子和一个2,5 - 二甲基吡嗪配体以及占据一般位置的一个溴离子组成。镉阳离子在略微扭曲的 -CdBrN八面体中由四个溴离子和两个2,5 - 二甲基吡嗪配体进行六配位。阳离子通过成对的桥连溴离子连接成[100]链，这些链再通过桥连的2,5 - 二甲基吡嗪配体进一步连接成(001)层。粉末X射线衍射（PXRD）表明已获得纯晶相。热重分析与差示热分析联用（TG - TDA）显示，2,5 - 二甲基吡嗪配体分两步去除，形成组成为(CdBr)(2,5 - 二甲基吡嗪)的化合物，该化合物在进一步加热时分解为CdBr。第一次质量损失后所得残余物的PXRD测量表明形成了新的晶相。
