Summary New complexes of copper(I) with some heterocyclic pentatomic rings, X·CH2·CH2·NR·CSe, where X=CH2, NH, NMe, NEt, S and R=H, Me, Et, were prepared by reacting copper(II) chloride and bromide in MeOH. The stoichiometry of the complexes and the binding mode of the ligands have been discussed comparatively, together with those of the thione parents. It is noteworthy that the selone ligands with R=H (L) yield complexes of the type CuLnY, (n=1,2 or 3; Y=Cl or Br) like the corresponding thione ones. On the contrary, when R=Me or Et, the selonic ligands (L′) give complexes whose stoichiometries, Cu2L′Y2 and Cu3L′2Y3, differ from the thione homologues. The i.r. spectra of the complexes compared with those of the ligands support the coordinative bondvia selenium atom.
