Solid solutions of V x Co 1–x [TCNE] 2 composition have been prepared from the reaction of V(CO) 6 and Co 2 (CO) 8 in dichloromethane. All magnetically order above 280 K for x > 0.05 and their coercivity increases with decreasing x , reaching a maximum of 270 Oe for x = 0.3 (see Figure). Hence, the magnetic properties of this magnet can be finely tuned via a synthetic organic chemistry methodology.
