Organic- and polymeric-based materials exhibiting the technologically important cooperative property of ferromagnetism have been discovered in the past decade and studied. Several magnets based on the tetracyanoethylenide radical anion, [TCNE]{sup -}, have been prepared in or laboratory. These include [TCNE]{sup -} electron transfer salts decamethylmetallocenes (T{sub c} <10 K), coordination polymers based on metallomacrocycles, and 3-D network polymers with vanadium. The latter is a polymeric magnet which has been characterized to have a critical temperature, T{sub c}, above 350 K. The chemistry and physical properties, with emphasis on the structure-function relationship, for this class of materials will be discussed.
