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.

[1] 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).
