Abstract

A C,S bonded quasi-two-coordinate Cr(II) complex, Cr(SAr*)₂ (HSAr* = HSC₆H₃-2,6(C₆H₂-2,4,6-Prⁱ₃)₂), has been synthesized according to literature precedent. Magnetic measurements, high-frequency/field electron paramagnetic resonance (HF-EPR) experiments and ab initio calculation studies show that the field-induced slow magnetic relaxation behaviour is caused by relatively weak axial magnetic anisotropy.
