The reactivity of the asymmetric thioether 1,3-bis(2-pyridyl)-1-thiapropane [1-(2-pyridyl)-2-(2-pyridyl-sulfanyl)ethane] (bpt) with copper-(I) and -(II) starting materials has been investigated. Reaction with [Cu(NCMe)4]PF6 in MeCN gave a cluster formulated as [Cu4(bpt)6][PF6]4, whilst reaction in tetrahydrofuran resulted in partial cleavage of bpt to give the mixed thionato-thioether complex [Cu2(SC5H4N)(bpt)]PF6 [SC5H4NH = pyridine-2(1H)-thione]. Reaction with [Cu2(μ-O2CMe)4] in MeOH gave the dimer [{Cu(μ-O2CMe)2-(bpt)}2], whose crystal structure shows that the bpt ligands are monodentate and co-ordinated via the N atom remote from the thioether. The compound bpt undergoes cleavage with other copper(II) salts such as Cu(BF4)2, ultimately giving the hexameric copper(I) complex [Cu6(SC5H4N)6]. The details of this reaction have been investigated. Reaction of SC5H4NH with Cu(NO3)2 in the presence of HNO3 gave [Cu(NO3)(SC5H4NH2)], which in turn reacted progressively with PPh3 to give [Cu(NO3)(SC5H4NH)2(PPh3)] and the known complex [Cu(SC5H4NH)2(PPh3) 2]NO3, whose crystal structure has been determined. Other complexes of SC5H4NH with copper(I) and a range of anions have been prepared, and the crystal structure of the dimer [Cu2(SC5H4NH)6]-[MeC 6H4SO3]2 is reported.
