Dinuclear copper(II) complexes incorporating a new pyrazolo-based sulfur-containing binucleating ligand

Di- and tri-organotin(IV) complexes of the new bis(1-methyl-1H-imidazol-2-ylthio)acetate ligand and the decarboxylated analogues

“…In recent years, a number of authors [25][26][27][28][29][30][31][32][33][34] have synthesized S,N-ligands of the type (CH 2 ) n (SAz) 2 based on a nitrogenated aromatic ring system such as benzimidazole or pyridine. These ligands are able to coordinate by both S and the neighbouring N atom, and hence to form stable chelate rings of five or more atoms [35][36][37][38][39][40][41].…”

Synthesis and characterisation of organotin(IV) derivatives of ambidentate ligands containing nitrogen and sulphur donor atoms

“…In this context, (S,N)-compounds are motivating because of being fl exible ligands and presenting a contrasting hardness and softness property between sulphur and nitrogen atoms. Complexes of the fi rst and second row of transition metals with tris-and bis(pyridin-2-ylthio)methane have been reported (Adhikary and Lucas , 1994 ;Barclay et al , 1998 ;Matthews et al , 1998 ;Chou et al , 1999 ). These ligands are capable of coordinating to metal centres, leading to stable chelating rings.…”
