摘要：

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. Copyright © 2012 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
