报道了孔隙率为 80 % 的氢键离子固体的独特例子，[Co(H2O)6]3[Co2Au3(d-pen-N,S)6]2(1;d-H2pen=d-青霉胺)，由 [Co(H2O)6]2+ 阳离子和 [Co2Au3(d-pen-N,S)6]3− 阴离子组成。 Solid1是通过动力学产生的，然后通过游离羧酸基团的配位，逐步转化为两种具有较低孔隙率的热力学稳定固体，[Co(H2O)4][Co(H2O)6]2[Co2Au3(d-pen-N,S)6]2(2)和[Co(H2O)4]3[Co2Au3(d-pen-N,S)6]2(3)。 [Co2Au3(d-pen-N,S)6]3− 到 CoII 中心。对固体 1-3 进行了结构表征，并研究了小分子选择性吸附到其孔隙中的情况。
A unique example of a hydrogen‐bonded ionic solid with a porosity of 80 %, [Co(H2O)6]3[Co2Au3(d‐pen‐N,S)6]2(1;d‐H2pen=d‐penicillamine), composed of [Co(H2O)6]2+cations and [Co2Au3(d‐pen‐N,S)6]3−anions, is reported. Solid1was kinetically produced and was then transformed stepwise into two more thermodynamically stable solids with lower porosities, [Co(H2O)4][Co(H2O)6]2[Co2Au3(d‐pen‐N,S)6]2(2) and [Co(H2O)4]3[Co2Au3(d‐pen‐N,S)6]2(3), through the coordination of the free carboxylate groups in [Co2Au3(d‐pen‐N,S)6]3−to CoIIcenters. Solids1–3were structurally characterized, and the selective adsorption of small molecules into their pores was investigated.
