Tm ligands

Tm is an abbreviation for anionic tridentate ligand based on three imidazole-2-thioketone groups bonded to a borohydride center.

Various ligands in this family are known, differing in what substituents are on the imidazoles.

Salts of the TmMe anion are known also for lithium and potassium.

Other alkyl- and aryl-group variations are likewise named TmR according to those groups.

The thioamide sulfur is highly basic, as found for other thioureas.
