“…The Cu(3)···Cu(3‘) separation [2.9832(9) Å], while representing the shortest intermetallic distance in Cu 3 {MeSi(CH 2 SMe) 3 } 2 Br 3 , indicates at most a weak copper−copper interaction. The Cu−S bond lengths (in the approximate range 2.29−2.43 Å) are within the range of the values observed for other Cu(I) thioether complexes. − ,,,− Likewise, the Cu−Br bond distances, between 2.419(1) and 2.563(1) Å, appear to be normal, , as are the S−C and Si−C bond lengths (ca. 1.81 and 1.88 Å, respectively) …”

“…Molecular architecture and self-assembly of complex structures are two of the most fascinating themes in modern inorganic chemistry. − Among the transition metals, copper(I) has played a central role in the construction of supramolecular arrays supported by a variety of nitrogen and sulfur donor ligands − a number of species exhibiting extended solid-state structures have been reported for derivatives of polydentate or macrocyclic thioethers. − With the aim of exploring the chemistry of new acyclic polythioether ligands, we recently prepared the new tridentate thioether MeSi(CH 2 SMe) 3 (Chart A) and structurally characterized its octahedral group 6 metal carbonyl derivatives {η 3 -MeSi(CH 2 SMe) 3 }M(CO) 3 (M = Cr, Mo, W) . It occurred to us that the enhanced structural flexibility of MeSi(CH 2 SMe) 3 compared to that of related “crown” thioethers such as 1,4,7-trithiacyclononane (commonly abbreviated ttcn or 9S3, Chart B) may facilitate the preparation of complexes with different coordination geometries and novel structures.…”

The one-dimensional copper(I) coordination polymers Cu(3){MeSi(CH(2)SMe)(3)}(2)X(3) (X = Cl, Br) and [{MeSi(CH(2)SMe)(3)}Cu(NCMe)]Y (Y = OSO(2)CF(3), BF(4), PF(6)) were readily obtained in very good to excellent yields (80-95%) by reacting CuX or [Cu(NCMe)(4)]Y, respectively, with the tridentate thioether ligand MeSi(CH(2)SMe)(3) in acetonitrile. The new complexes were characterized by a combination of analytical and spectroscopic techniques, including electrospray ionization mass spectrometry and, for the bromo and hexafluorophosphate derivatives, single-crystal X-ray diffraction. Both complexes exhibit one-dimensional chain structures with approximately tetrahedral copper centers and bridging unidentate/bidentate thioether ligands.

“…For example, compound VII herein represents the first magnetostructural study of a binuclear oxygen-bridged copper(II) species with NSO 3 Br coordination spheres. Thus, this paper represents part of our continuing interest [9][10][11][12] in the consequences of molecular changes upon properties that manifest themselves at the macroscopic level.

Single crystal X-ray structural studies for I, III and VII are reported. Variable temperature magnetic susceptibility studies of I, VI and VII are discussed. The examination of VII represents the first magneto-structural study of a binuclear copper(II) species with NSO3Br coordination spheres. This study examines perturbation by one or more of the donor atoms so that none of the known magnetostructural models predicts the copper-copper coupling.Résumé : Utilisant les 1,11-bis(salicylaldimine)-3,6,9-trithiaundécane (H2L1), 1,11-bis(salicylaldimine)-6-oxa-3,9-dithiaundécane (H2L2) et 1,8-bis(salicylaldimine)-3,6-dithiaundécane (H2L3), on a réalisé les synthèses des complexes [Cu(L1)]2 (I), Cu(L2)·CH3OH (II), Cu(L3) (III), [Cu(HL3)][CH3COO] (IV), [Cu(HLI-sal)]Cl2 (V), Cu4(L1)2Br5(H2O)2·2H2O (VI) et Cu2(L2)Br2·xH2O (VII). On a effectué la détermination des structures des composés I, III et VII par diffraction des rayons-X sur un cristal unique. On discute des résultats d'études de susceptibilité magnétique des composés I, VI et VII, à tempé-rature variable. L'examen du composé VII correspond à la première étude magnéto-structurale d'une espèce de cuivre(II) binucléaire comportant des sphères de coordination avec du NSO3Br. Cette étude permet d'examiner la perturbation par un ou plusieurs atomes donneurs; aucun des modèles magnéto-structuraux ne prédit le couplage cuivre-cuivre.Mots-clés : complexes de cuivre(II) binucléaire, thioéther, ligands salicylaldimine, susceptibilité magnétique à température variable, corrélation magnéto-structurale, structure par diffraction des rayons X.[Traduit par la Rédaction]

Characterization of cobalt(II), cadmium(II), copper(II) and tin(II) cinnarizine complexes have been carried out using conductivity, electronic spectra, infrared, nmr, thermogravimetric and Xray analyses to establish the nature of phase stabilization in these materials. Also, the intrinsic strain components present in these materials during the formation have been computed using wide-angle X-ray scattering analysis. The variation of the crystallite shape ellipsoid in these materials has been discussed on the basis of Hosemann's paracrystalline model.
