Abstract

The asymmetric unit of the title compound, [(CH(3))(2)NH(CH(2))(2)NH(CH(3))(2)][CoCl(4)], contains a tetra-chlorido-cobalt-ate(II) dianion and two halves of two centrosymmetric, crystallographically-independent, dications. One independent dication is disordered between two conformations in a 0.784 (13):0.216 (13) ratio. In the crystal, inter-molecular N-H⋯Cl hydrogen bonds link cations and anions into chains propagated in [01]. These hydrogen bonds contribute to the distorted tetra-hedral geometry at the Co(II) atom.

摘要

标题化合物[(CH₃)₂NH(CH₂)₂NH(CH₃)₂][CoCl₄]的不对称单元包含一个四氯合钴(II)二价阴离子以及两个中心对称、晶体学独立的二价阳离子的一半。一个独立的二价阳离子在两种构象之间无序分布，比例为0.784 (13):0.216 (13)。在晶体中，分子间的N—H⋯Cl氢键将阳离子和阴离子连接成沿[01]方向延伸的链。这些氢键导致Co(II)原子处的四面体几何构型发生扭曲。
