Abstract

(Figure Presented) A spin-crossover from Fe ^II (S = 2)-Nb ^IV -(S = 1/2)-Fe ^II (S = 2) to Fe ^II (S = 0)-Nb ^IV -(S = 1/2)-Fe ^II (S = 2) occurs in Fe ₂ [Nb(CN) ₈ ]·3-pyCH ₂ OH) ₈ ·.6H ₂ O (3-py = 3-pyridyl) with decreasing temperature (see picture; red Fe, blue Nb). The low-temperature phase shows ferrimagnetism with a Curie temperature of 12 K owing to an antiferromagnetic interaction between the remaining Fe ^II (S = 2) and the Nb ^IV (S = 1/2) centers.
