Iron bis(diethyldithiocarbamate) is a coordination complex with the formula where Et = ethyl (). A red solid, iron bis(diethyldithiocarbamate) is representative of several ferrous dithiocarbamates with diverse substituents in place of ethyl. In terms of structure, the species is dimeric, consisting of a pair of pentacoordinate iron(II) centers. It is structurally related to zinc bis(dimethyldithiocarbamate).
The complex reacts with a variety of reagents with concomitant formation of mono-iron derivatives. It adds 9,10-phenanthroline (phen) to give the blue-octahedral complex . 3,4-Bis(trifluoromethyl)-1,2-dithiete reacts to give the Fe(IV) dithiolene complex . Nitric oxide and carbon monoxide add to give the nitrosyl complex and the carbonyl complex , respectively.
