A C,S bonded quasi-two-coordinate chromium(ii) complex showing field-induced slow magnetic relaxation behaviour

A C,S bonded quasi-two-coordinate Cr(ii) complex, Cr(SAr*)(2) (HSAr* = HSC6H3-2,6(C6H2-2,4,6-Pr-3(i))(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.
