A new organically templated vanadium tellurite, poly[2,2'-iminodiethanaminium [hexa-mu2-oxido-tetraoxidoditellurium(IV)divanadium(V)] dihydrate], {(C4H15N3)[Te2V2O10].2H2O}n, features the interconnection of distorted [VO5] trigonal bipyramids by bridging [TeO3] pyramids, leading to a two-dimensional corrugated anionic layer with an interlayer distance of about 13.47 A. The interlayer space is occupied by doubly protonated diethylenetriamine cations (H2dien) and guest water molecules. The two terminal amino groups of H2dien are protonated, while the middle amino group, located on a twofold rotation axis, is not protonated. All the three amino groups and water molecules are involved in hydrogen-bonding interactions. The compound represents a new member in the series (H2am)[(VO2)(TeO3)]2.xH2O, where H2am represents a doubly protonated diamine. Similarities and differences between the structures of members of the series are discussed.
一种新型的有机模板碲酸钒,聚[2,2'-亚氨基二乙铵[六-μ2-氧代-四氧化二碲(IV)二钒(V)]二水合物],{(C4H15N3)[Te2V2O10].2H2O}n,其特征在于通过桥连的[TeO3]金字塔使扭曲的[VO5]三角双锥体相互连接,形成二维波纹状阴离子层,层间距约为13.47 Å。层间空间由双质子化的二乙烯三胺阳离子(H2dien)和客体水分子占据。H2dien的两个末端氨基被质子化,而位于二重旋转轴上的中间氨基未被质子化。所有三个氨基和水分子都参与氢键相互作用。该化合物代表了系列(H2am)[(VO2)(TeO3)]2.xH2O中的一个新成员,其中H2am代表双质子化的二胺。讨论了该系列成员结构之间的异同。
