Does Thiotimolene crystallize, if so what is its structure? It cannot be face-centered cubic, it must be a face-centered tesseract.

Re: Practical space-time crystals
So, referenced to a spatially nontranslating and nonrotating frame (say, one fixed w.r.t. distant stars, a.k.a. "operationally inertial"), a spatially nontranslating but spatially rotating space-time crystal is periodic both in space (at any instant of time) and in time (at any location in space through which any part of the crystal rotates).
Referenced to a frame fixed to the spatially-rotating arrangement of ions (rotating w.r.t. distant stars, thus non-inertial), a space-time crystal is periodic only in space and static (aperiodic) in time.
