Abstract

Despite significant structural rearrangement upon desolvation of a three-dimensional molecular framework of hexaaquacobalt cations and redox-active functionalized tetrathiafulvalene anions (see the picture; the area filled with water molecules is shown in gray), monocrystallinity and microporosity are retained. X-ray analyses show that a unique combination of hydrogen bonds and π⋅⋅⋅π interactions within the framework gives this material a structural flexibility not seen in zeolites or their analogues.

Keywords: Crystal engineering; Hydrogen bonds; Microporosity; Redox chemistry; Tetrathiafulvalene.
