Tunable Raman Scattering of Fe(II) Coordination Networks With Magnetic Fields

ABSTRACT Controlling terahertz (THz) waves is important for next‐generation communications, sensing, and imaging technologies. However, it is still unclear precisely how THz signals can be manipulated by various materials. Herein, we report the design and synthesis of four coordi...

A ComplexSpin-Transition Thermal Hysteresis Unlockedby Two Competing Symmetry-Breakings

Abstract The spin-crossover material [Fe(NH2trz)3](NO3)2 belongs to the class of 1D triazole-based polymeric SCO complexes. It exhibits a thermal phase transition, with a 28 K wide thermal hysteresis, characterized by phase transition temperatures T↑ = 346 K upon warming and T↓ =...
