The compounds [{HgL¹(NO₃)_∝] (L¹ = 6-oxa-3,9-dithiabicyclo[9,3,1] pentadeca-1(15),11,13-triene) (1), [{AgL²(NO₃)} _∝] (L² = (1,3-bis(phenylthio)methyl) benzene) (2), [(HgL³Cl₂}₂] and [{CuL³Cl}_∝ (L³ = (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 three-dimensional polymer. Each Cu¹ cation has a distorted tetrahedral environment defined by two sulfur atoms of different L³ 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.
