A scissor‐like geometric mechanism is responsible for the strongest negative linear compression effect yet observed in a molecular material, [Fe(dpp) 2 (NCS) 2 ]⋅py (see picture; dpp=dipyrido[3,2‐ a :2′3′‐ c ]phenazine), C gray, N blue, S yellow, Fe red). The same mechanism is also responsible for suppressing the high‐spin to low‐spin transition under pressure.
