'''Sodium diethyldithiocarbamate''' is the ] with the formula NaS<sub>2</sub>CN(C<sub>2</sub>H<sub>5</sub>)<sub>2</sub>. It is a pale yellow, water soluble salt. |

|
==Preparation== |
|
|
Sodium diethyldithiocarbamate typically crystallizes from water as the trihydrate NaS<sub>2</sub>CN(C<sub>2</sub>H<sub>5</sub>)<sub>2</sub><sup>'''.'''</sup>3H<sub>2</sub>O. The anhydrous salt and the trihydrate are often used interchangeably.<ref>{{cite journal |doi=10.1016/s0020-1693(00)84914-2 |title=Hydrogen bonds in sodium dialkylthiocarbamate hydrates.

Sodium diethyldithiocarbamate is obtained by treating ] with ] in the presence of ]: |
|
|
:CS<sub>2</sub> + HN(C<sub>2</sub>H<sub>5</sub>)<sub>2</sub> + NaOH → NaS<sub>2</sub>CN(C<sub>2</sub>H<sub>5</sub>)<sub>2</sub> + H<sub>2</sub>O |
|
|
Other ]s can be prepared similarly from secondary amines and carbon disulfide. They are used as ] for transition metal ions and as precursors to ]s and ] reagents. |

Dithiocarbamates are nucleophiles and thus can be alkylated. Even ] suffices:<ref>{{cite journal |doi=10.1139/v70-645|title=Reactions of Sodium ''N,N''-Diethyldithiocarbamate with Some Organic Solvents |year=1970 |last1=Heckley |first1=P.

Diethyldithiocarbamate reacts with many metal salts to give ]. The ligands coordinate via the two sulfur atoms. Other more complicated bonding modes are known including binding as unidentate ligand and a ] using one or both sulfur atoms.<ref>{{Cotton&Wilkinson6th}}</ref> |

==Laboratory and practical use== |
|
|
By the technique of ], complexes of dithiocarbamates with iron provide one of the very few methods to study the formation of ] (NO) radicals in biological materials. Although the lifetime of NO in tissues is too short to allow detection of this radical itself, NO readily binds to iron-dithiocarbamate complexes. The resulting mono-nitrosyl-iron complex (MNIC) is stable, and may be detected with ] (EPR) spectroscopy.<ref>Henry Y.; Guissani A.; Ducastel B.
