Chiral nanotube: A flexible porous homochiral SrSi 2 framework of two types of single‐stranded helical nanotubes is presented (see structure). The Cu I ions in the framework can be oxidized to Cu II through single‐crystal‐to‐single‐crystal transformation forming a new, topologically equivalent phase, accompanied by an expansion in the unit cell volume of 12.51 %.
