Abstract

The asymmetric unit of the organic-inorganic title salt, (C10H28N4)[Cr2O7]2, comprises one half of an 1,4-bis-(3-ammonio-prop-yl)piperazinediium cation (the other half being generated by the application of inversion symmetry) and a dichromate anion. The piperazine ring of the cation adopts a chair conformation, and the two CrO4 tetra-hedra of the anion are in an almost eclipsed conformation. In the crystal, the cations and anions form a layered arrangement parallel to (001). N-H⋯O hydrogen bonds between the cations and anions and additional C-H⋯O inter-actions lead to the formation of a three-dimensional network structure.

摘要

有机-无机标题盐（C₁₀H₂₈N₄）[Cr₂O₇]₂的不对称单元包含一个1,4-双（3-氨丙基）哌嗪二铵阳离子的一半（另一半通过倒转对称性产生）和一个重铬酸根阴离子。阳离子的哌嗪环呈椅式构象，阴离子的两个CrO₄四面体几乎呈重叠构象。在晶体中，阳离子和阴离子形成平行于（001）的层状排列。阳离子和阴离子之间的N-H⋯O氢键以及额外的C-H⋯O相互作用导致形成三维网络结构。
