Fe II L 2 (OTf) 2 ( 1 ) and Mn II L 2 (OTf) 2 ( 2 ) (L = tris(1‐ethyl‐4‐methylimidazolyl‐κN)phosphine; OTf= trifluoromethanesulfonate) were synthesized and their X‐ray structures were determined. Both complexes possess distorted octahedral geometry with high spin electron configuration at ambient temperature. Compound 1 exhibits a quasi‐reversible wave with E 1/2 of 0.745 V versus Ag/AgNO 3 . Variable temperature magnetic measurements indicate that no spin‐crossover phenomenon for 1 is observed between 2.5 and 300 K. In addition, a plot of 1/χ M versus T(K) is linear with a Curie constant of 3.48 emu mol −1 K.
