The title compound, C(16)H(26)N(4) (4+)·4Cl(-), is based on a fully protonated tetra-amine. In the cation, both benzene rings are connected by an all-trans chain, and the rings are almost parallel, with an angle between the mean planes of 8.34 (12)°. The benzene rings are arranged in such a way that the NH(3) (+) substituents are oriented cis with respect to the central chain. This arrangement is a consequence of multiple N-H⋯Cl hydrogen bonds, involving all N-H groups in the cation and the four independent Cl(-) anions. These contacts have strengths ranging from weak to strong (based on H⋯Cl separations), and generate a complex three-dimensional crystal structure with no preferential crystallographic orientation for the contacts.
标题化合物C(16)H(26)N(4)(4+)·4Cl(-)基于一个完全质子化的四胺。在阳离子中,两个苯环通过一条全反式链相连,且环几乎平行,平均平面间的夹角为8.34 (12)°。苯环的排列方式使得NH(3)(+)取代基相对于中心链呈顺式取向。这种排列是多个N - H⋯Cl氢键作用的结果,涉及阳离子中的所有N - H基团和四个独立的Cl(-)阴离子。这些接触的强度从弱到强(基于H⋯Cl间距),并产生一个复杂的三维晶体结构,接触没有优先的晶体学取向。
