Nb 3 SI 7 layers with a new structural modification and the first‐ever observed trigonalbipyramidal NbI 5 monomers found in nearly hexagonal channels (see the structure on the right) characterize the title compound. According to physical measurements and structural calculations, these two components, which are unstable alone, are held together primarily by van der Waals and other dispersion forces.
