Abstract
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.Keywords
