Synthesis, structure and magnetic characterization of decamethylmetallocenium ethyl tricyanoethylenecarboxylate charge-transfer salts

A new family of metallocene charge-transfer salt magnets has been synthesized and characterized based on a new organic one-electron acceptor, ethyl tricyanoethylenecarboxylate, ETCE, which is a homolog of methyl tricyanoethylenecarboxylate. Magnetic measurements indicate that ordering occurs at low temperatures.
