Dichlorobis[(S)-2,3,5,6-tetrahydro-6-phenylimidazo[2,1-b]thiazole]nickel(II)

Abstract

The title compound, [NiCl2(C11H12N2S)2], crystallizes with two independent mol­ecules per asymmetric unit. The Ni atom displays a pseudo‐tetra­hedral environment of the ligands, as expected for paramagnetic NiII compounds.

Methyl Levamisolium Triflate as a Precursor to a Chiral Bifunctional N-Heterocyclic Carbene-Thiolate Ligand: Palladium(II) Complexes

“…Very few inorganic derivatives of levamisole (lvms) have been reported. They are the complexes [MCl 2 (lvms) 2 ] (M = Co, Ni, Cu, Zn), [Pd(aminoacidato)(lvms)]Cl, and [PtCl(en)(lvms)]Cl (en = ethylendiamine), which all have the levamisole ligand coordinated through the sp 2 N atom. A triruthenium derivative that results from the cleavage of the C−S bond of levamisole hydrochloride has also been reported …”

Sulfur-functionalized N-heterocyclic carbenes and their transition metal complexes

“…Typically, neutral (−)-levamisole (10) does not undergo C-S bond activation, and binds through the sp 2 nitrogen as a two electron donor to metals such as Co, Ni, Cu, Zn, Pd and Pt [53][54][55][56]. C-S activation was only observed in Pd, Ru, and Os complexes involving the cationic ligand 10·HCl or the N-methylated derivative (11) [48][49][50].…”
