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.
