The preparation and X-ray crystal structures of (CyNC)Au(I)CN, (n-BuNC)Au(I)CN, and (i-PrNC)Au(I)CN.0.5CH(2)Cl(2) are reported and compared with those of (MeNC)Au(I)CN and (t-BuNC)Au(I)CN, which were previously described. These linear molecules are all organized through aurophilic interactions into three structural classes: simple chains ((CyNC)Au(I)CN and (t-BuNC)Au(I)CN), side-by-side chains in which two strands make Au...Au contact with each other ((n-BuNC)Au(I)CN), and nets in which multiple aurophilic interactions produce layers of gold(I) centers ((i-PrNC)Au(I)CN and (MeNC)Au(I)CN). All of these five solids dissolve to produce colorless, nonluminescent solutions with similar UV/vis spectra. However, each of the solids displays a unique luminescence with emission maxima occurring in the range 371-430 nm.
报道了（环戊腈）金（I）氰化物、（正丁腈）金（I）氰化物和（异丙腈）金（I）氰化物·0.5二氯甲烷的制备及其X射线晶体结构，并与先前描述的（甲基腈）金（I）氰化物和（叔丁腈）金（I）氰化物进行了比较。这些线性分子均通过亲金相互作用形成三种结构类型：简单链状结构（（环戊腈）金（I）氰化物和（叔丁腈）金（I）氰化物）、两条链相互形成金……金接触的并排链状结构（（正丁腈）金（I）氰化物）以及通过多个亲金相互作用产生金（I）中心层的网状结构（（异丙腈）金（I）氰化物和（甲基腈）金（I）氰化物）。这五种固体均能溶解，形成具有相似紫外/可见光谱的无色、不发光的溶液。然而，每种固体都显示出独特的发光现象，发射最大值出现在371 - 430 nm范围内。
