Vanadium pentacyanonitrosylmolybdate-based magnet exhibiting a high magnetic ordering temperature of 200Â K

Vanadium pentacyanonitrosylmolybdate, K0.82V1.06[Mo(CN)5(NO)]·3.8H2O, synthesized from K4[Mo(CN)5(NO)]·2H2O and VCl3, has a face-centered cubic crystal structure with a lattice constant of 10.410(8) Å, and shows ferrimagnetism with a high Curie temperature of 200 K, in which the magnetic spins on VII (S = 3/2) and VIII (S = 1) antiparallely align with the spins on MoI (S = 1/2). 84
