Abstract

The reaction of 2,3,5,6-tetracyanopyridine (TCNPy) with V(CO)6 in CH2Cl2 forms new organic-based magnets of V[TCNPy]x•z(CH2Cl2) (x = 2, 3) composition. Analysis of the IR spectra suggests that the TCNPy is reduced and coordinated to V(II) sites via the nitriles. V[TCNPy]x order as ferrimagnets with 111 and 90 K Tc's for V[TCNPy]2 and V[TCNPy]3, respectively. Their respective remanant magnetizations and coercive fields are 1310 and 240 emuOe/mol and 9 and 6 Oe at 5 K, and they exhibit some spin glass behavior.
