“…In the case of Cu(II), the formation of Cu(SCN) 2 is immediately followed at elevated temperatures by disproportionation to the insoluble Cu(I) complex CuSCN (and indeed this is a common technique for the gravimetric determination of copper). 75 Cuprous thiocyanate will thus be the major product obtained at temperatures sufficient to promote the thiourea/ammonium thiocyanate isomerisation but not enough to completely decompose the thiourea.…”

“…Analytical-grade solvents were used without further purification; Cu I halides, CuSCN and [Cu I (MeCN) 4 ]PF 6 were prepared according to literature preparations (Kauffman & Pinnell, 1960;Keller & Wycoff, 1946;Kubas et al, 1990;Newman, 1963); and t BuXPhos and Cu(ClO 4 ) 2 Á6H 2 O were purchased from Sigma-Aldrich. Reactions were carried out under an N 2 atmosphere.…”

CuI complexes containing the bulky dialkylbiarylphosphane 2-(di-tert-butylphosphanyl)-2′,4′,6′-triisopropylbiphenyl ( t BuXPhos, L) and an ancillary ligand (Cl−, Br−, I−, MeCN, ClO4 − or SCN−) have been structurally characterized, namely, chlorido[2-(di-tert-butylphosphanyl)-2′,4′,6′-triisopropylbiphenyl-κP]copper(I), [CuCl(C29H45P)], 1, bromido[2-(di-tert-butylphosphanyl)-2′,4′,6′-triisopropylbiphenyl-κP]copper(I), [CuBr(C29H45P)], 2, [2-(di-tert-butylphosphanyl)-2′,4′,6′-triisopropylbiphenyl-κP]iodidocopper(I), [CuI(C29H45P)], 3, (acetonitrile-κN)[2-(di-tert-butylphosphanyl)-2′,4′,6′-triisopropylbiphenyl-κP]copper(I) hexafluoridophosphate, [Cu(CH3CN)(C29H45P)]PF6, 4, [2-(di-tert-butylphosphanyl)-2′,4′,6′-triisopropylbiphenyl-κP](perchlorato-κO)copper(I), [Cu(ClO4)(C29H45P)], 5, and di-μ-thiocyanato-κ2 S:N;κ2 N:S-bis{[2-(di-tert-butylphosphanyl)-2′,4′,6′-triisopropylbiphenyl-κP]copper(I)}, [Cu2(NCS)2(C29H45P)2], 6. Iodide complex 3 shows significant CuI–arene interactions, in contrast to its chloride 1 and bromide 2 counterparts, which is attributed to the weaker interaction between the iodide ion and the CuI centre. When replacing iodide with an acetonitrile (in 4) or perchlorate (in 5) ligand, the reduced interaction between the CuI atom and the ancillary ligand results in stronger CuI–arene interactions. No CuI–arene interactions are observed in dimer 6, due to the tricoordinated CuI centre having sufficient electron density from the coordinated ligands.
