Iron tris(dimethyldithiocarbamate)

Iron tris(dithiocarbamate)s are typically are prepared by salt metathesis reactions.{{cite book|chapter=The Chemistry of the Dithioacid and 1,1-Dithiolate Complexes|title=Progress in Inorganic Chemistry|volume=11|author=D.

Iron tris(dimethyldithiocarbamate) is an octahedral coordination complex of iron(III) with D₃ symmetry.{{cite journal|title=Compounds with intermediate spin. I.

Spin crossover (SCO) was first observed in 1931 by Cambi et al. who discovered anomalous magnetic behavior for the tris(N,N-dialkyldithiocarbamatoiron(III) complexes.{{cite journal|author1=L.

Iron tris(dithiocarbamate)s react with nitric oxide to give a nitrosyl complex:

This efficient chemical trapping reaction provides a means to detect NO.{{cite journal|author1=Fujii, S. |author2=Yoshimura, T. |title=A New Trend in Iron–Dithiocarbamate Complexes: as an Endogenous NO Trapping Agent|journal=Coordination Chemistry Reviews|year=2000|volume=198|pages=89–99|doi=10.1016/S0010-8545(99)00196-4}}

Reflecting the strongly donating properties of dithiocarbamate ligands, iron tris(dithiocarbamate)s oxidize at relatively mild potentials to give isolable iron(IV) derivatives [Fe(S₂CNR₂)₃]⁺.{{cite journal|author1=Pasek, E.

Iron tris(dithiocarbamate)s react with hydrochloric acid to give the pentacoordinate chloride:{{cite journal |doi=10.1021/ic50050a016|title=A Novel Series of fFive-Coordinated Iron(III) Complexes with the Square-Pyramidal Configuration and Spin, S = 3/2 |year=1967 |last1=Martin |first1=R.

The U.S. Occupational Safety and Health Administration (OSHA) has set the legal (permissible exposure limit) for ferbam exposure in the workplace as 15 mg/m³ over an 8-hour workday. The U.S. National Institute for Occupational Safety and Health (NIOSH) has set a recommended exposure limit (REL) of 1 mg/m³ over an 8-hour workday. At levels of 800 mg/m³, ferbam is immediately dangerous to life and health.
