Magnetically ordered Ni[TCNE]2 · zCH2Cl2 (Tc = 13 K) is reported for the first time from the reaction of Ni(CO)4 with tetracyanoethylene (TCNE). A family of new solid solution room temperature magnets of VxNi1 − x[TCNE]y · zCH2Cl2 (0 ≤ x 0; however, the magnitude of M increases with x, as does the broadness of the peaks in the χ′(T) and χ″(T) ac susceptibilities. Hence, the magnetic properties of the room temperature V[TCNE]y · zCH2Cl2 magnet can be finely tuned via synthetic chemistry methodology, making this material more amenable in future technologies. |
