Several tetracyanocarbon based magnets were synthesized and magnetically characterized. [FeCp*2] [TCNE] (Cp* = pentamethylcylcopentadienyl, TCNE = tetracyanoethylene), the first organic-based magnet, with a critical temperature, Tc = 4.8 K was further explored using AC susceptibility measurements looking at the effect various nitrile solvents had on Tc for [FeCp*2][TCNE]•S (S = MeCN, EtCN, PrCN, PhCN, NCC4H8CN and 1.2-C 6H4Cl2). Regardless of the solvent, the Tc decreased and a spin-glass like behavior was observed. The related [FeCp*2][TCNQ], (TCNQ = 7,7,8,8-tetracyano p-quinodimethane) has metamagnet (Tc = 2.6 K) and ferromagnet (Tc = 3.1 K) polymorphs. Each magnetic phase was magnetically characterized in detail using AC susceptibility (varying both temperature and field), heat capacity, and isothermal magnetization resulting in the construction of a magnetic phase diagram. The magnetic phase diagram contains a paramagnetic, an antiferromagnetic, and an intermediate phase. V(CO)6 was reacted with two equivalents of TCNB (TCNB = tetracyanobenzene) in CH2Cl2, which led to a new family of room temperature magnets with (Tc &sim; 325 K. These systems were magnetically characterized using zero field/field cooled, isothermal magnetization and AC susceptibility. The systems were physically characterized using infrared spectra, elemental analysis, thermogravimetric analysis and high resolution mass spectra.
