Abstract

A room-temperature magnet of V[MeTCEC]2·0.6(CH2Cl2) composition (MeTCEC = methyl tricyanoethylenecarboxylate) is formed by the reaction of MeTCEC and V(CO)6 (see figure). Analysis of the magnetization indicates a less disordered structure of V[MeTCEC]2·0.6(CH2Cl2) with respect to similarly synthesized V[TCNE]x·0.34(CH2Cl2), presumably because of the much slower reaction of MeTCEC and V(CO)6.
