The title compound, (C(8)H(16)N)(2)[PbI(4)], crystallizes as an inorganic-organic hybrid perovskite, adopting the unusual 2a(p) x 2a(p) superstructure. As such, the structure consists of two-dimensional sheets of corner-sharing PbI(6) octahedra in the ab plane, separated by bilayers of 2-(1-cyclohexenyl)ethylammonium cations. The ethylammonium groups are not in the plane of the cyclohexenyl rings.
标题化合物(C₈H₁₆N)₂[PbI₄]以无机 - 有机杂化钙钛矿形式结晶,采用不寻常的2a(p)×2a(p)超结构。因此,该结构在ab平面上由角共享的PbI₆八面体的二维片层组成,被2-(1-环己烯基)乙铵阳离子双层隔开。乙铵基团不在环己烯基环的平面内。
