Slow Magnetic Relaxation in Silver(II) Macrocyclic Systems

[Image: see text] The spin–lattice relaxation time has been studied trough alternating-current susceptometry and ultralow-frequency Raman spectroscopy in a family of silver(II)-derived molecular systems with spin (1)/(2) and formulas [Ag(II)(m-CTH)(NO(3))(2)] (1) and [Ag(II)(m-CTH)(ClO(4))(2)] (2),...

description [Image: see text] The spin–lattice relaxation time has been studied trough alternating-current susceptometry and ultralow-frequency Raman spectroscopy in a family of silver(II)-derived molecular systems with spin (1)/(2) and formulas [Ag(II)(m-CTH)(NO(3))(2)] (1) and [Ag(II)(m-CTH)(ClO(4))(2)] (2), where CTH = meso-5,5,7,12,12,14-hexamethyl-1,4,8,11-tetraazacyclotetradecane. The combination of both techniques demonstrates the occurrence of slow spin magnetic relaxation induced by spin–phonon interaction. The magnetic behavior of these silver(II)-derived systems opens the door to a new cation in the scarce family of S = (1)/(2) systems with slow relaxation of magnetization.
