Di-μ-iodo-bis{[methyltris(methylthiomethyl)silane-κ²S,S′]copper(I)}

Abstract

The mol­ecule of the title compound, [Cu2I2(C7H18S3Si)2], is dimeric. It lies on an inversion center and contains roughly tetrahedral copper centers surrounded by two thio­ether groups and two bridging iodo ligands. The Cu⋯Cu separation, 2.862 (2) Å, is indicative of a weak interaction between the two metal atoms and is not unusual for this type of compound.

The four tin(IV) tetrahalide derivatives (Bts R )SnX 4 (X ¼ Cl, Br), which represent the first coordination complexes of these new thioether ligands, have also been successfully isolated and hint at the potential rich chemistry that this ligand system may support.…”

“…Although their coordination chemistry is yet to be fully exploited, a number of transition and main group metal complexes thereof have been synthesized in recent years, including group 6 metal tricarbonyl derivatives (Tts R )M(CO) 3 (M ¼ Cr, Mo, W) [1,2] and polynuclear compounds of copper(I) [3,4] and bismuth(III) [5]. The syntheses of the tetradentate thioethers Si(CH 2 SR) 4 (R ¼ Me, Ph) and their mercury(II) derivatives {Si(CH 2 SR) 4 }HgBr 2 , both of which exhibit one-dimensional polymeric structures in the solid state, have also been reported [6].…”

Formation of extended 1D coordination polymers in tetrathioether complexes of mercury(II): Effect of the organic substituents on the crystal structures of {Si(CH2SR)4}HgBr2 (R=Me, Ph)

“…3 The complexes present in the solid state extended structures in which fairly linear HgBr 2 moieties are connected by doubly bidentate chelating thioether ligands ( Figs. 1 and 2).…”

“…The extended structures result from intermolecular Hg-S interactions linking the monomeric {Si(CH 2 SR) 4 }HgBr 2 units, as established for 2a, b using single-crystal X-ray diffraction. The effective coordination around the Hg atoms in both compounds is best described as distorted octahedral.We have recently reported the synthesis of the bidentate and tridentate thioethers R 4 À n Si(CH 2 SR) n (n = 2, 3; R = Me, Ph) and characterized a wide variety of complexes in which they act as either terminal [1][2][3][4][5] or bridging ligands [6,7]. The latter are particularly interesting since flexible multidentate ligands have the ability to generate diverse coordination networks with potential applications as functional materials [8-10] but the use of polythioethers in such context has received little attention [11][12][13][14][15][16].…”

“…The tetrathioether Si(CH 2 SMe) 4 (1a) was easily synthesized, following a procedure similar to that used to prepare MeSi(CH 2 SMe) 3 [1], by reacting tetrachlorosilane with 4 molar equivalents of LiCH 2 SMe (Scheme 1). Following vacuum distillation (b.p.…”
