Iron bis(diethyldithiocarbamate)

Iron bis(diethyldithiocarbamate) is a coordination complex with the formula [Fe(S2CNEt2)2]2 where Et = C2H5. A red solid, it is representative of several ferrous dithiocarbamates with diverse substituents in place of ethyl. In terms of structure, the species is dimeric, consisting of two pentacoordinate iron(II) centers. It is isostructural with [Zn(S2CNEt2)2]2, which in turn is similar to zinc bis(dimethyldithiocarbamate).[1]

Reactions

The complex reacts with a variety of reagents with concomitant formation of mono-iron derivatives. 9,10-Phenanthroline adds to iron bis(diethyldithiocarbamate) to give the blue-octahedral complex [Fe(S2CNEt2)2](phen). 3,4-Bis(trifluoromethyl)-1,2-dithiete reacts to give the dithiolene complex [Fe(S2CNEt2)2](S2C2(CF3)2).[2] Nitric oxide and carbon monoxide to give the nitrosyl complex Fe(S2CNEt2)2NO and the carbonyl complex Fe(S2CNEt2)2(CO)2, respectively.
