Silver(I), mercury(II) and copper(I) complexes of acyclic and macrocyclic dithioether, metaxylyl based ligands

Abstract

The compounds [HgL 1(NO 3) χ ] (L 1 = 6-oxa-3,9-dithiabicyclo[9,3,1] pentadeca-l(15),11,13-triene) ( 1), [AgL 2(NO 3)} χ ] (L 2 = (1,3-bis(phenylthio)methyl) benzene) ( 2), [HgL 3Cl 2 2] and [CuL 3Cl} χ ] (L 3 = (1,3-Bis(ethylthio)methyl)benzene) ( 3) and ( 4) have been synthesized and their structures determined by X-ray crystallography. Compounds ( 1) and ( 2) have linear polymeric chains of alternating trigonal silver(I) cations and bridging ligands bonded through the sulfur atoms. In both structures the nitrate anion retains coordination to the silver atom. Compound ( 3) is a dimeric complex. Each mercury(II) cation is bound to two bridging chlorine atoms, one terminal chlorine atom and one sulfur atom from the ligand. Compound ( 4) is a threedimensional polymer. Each Cu 1 cation has a distorted tetrahedral environment defined by two sulfur atoms of different L 3 ligands and two bridging chlorine atoms. In each case the dithioether ligand acts as a bridging or monodentate ligand and does not chelate the metal.
