Abstract

Slow diffusion of AgNO3 with Me2Si(4-Py)2 yields an interwoven 2-nm-thick sheet consisting of the building block [Ag3(Me2Si(4-Py)2)4](NO3)3·H2O. The interweaving induces unique nanotunnels with a 16 × 18 Å2 cross section with a 7 × 8 Å2 square pore. The anion NO3- of the skeletal sheet can be reversibly exchanged with appropriately sized anions without the collapse of its structural integrity. The compound has a melting point (140 °C) and exists as the first 2D ionic liquid up to 193 °C.
