Homoleptic silver(I) complexes with dithio-, diseleno- and ditelluro-ethers: synthesis, structures and multinuclear nuclear magnetic resonance studies

Abstract

Homoleptic silver(i) complexes [Ag(L-L),]BF, {L-L = RE(CH,),ER [R = Ph or Me, n = 2 or 3 ( E = S or Se), n = 3 ( E = Te)]} have been prepared and characterised by analysis, FAB mass spectrometry, and multinuclear N M R spectroscopy ('H, "Se, lZ5Te and lo9Ag). Variable-temperature N M R studies c = 10.339(3) 1 , U = 2075.7(7) A3 [from 28 values of

1,10-Bis(phenylsulfanyl)decane

“…The S atom is a soft base and has a good ability to coordinate to Ag, which is a soft acid. In addition, the dithiolate building block can afford two coordination sites to a metal center and can be used to construct supramolecular architectures (Black et al, 1995;Bu et al, 2002). When the length of the aliphatic segment between the S atoms is increased, the number of possible conformations and the flexibility of the spacer are augmented.…”

Temperature‐Controlled Solvothermal Syntheses, Structures and Characterizations of a Novel Class of Zn Complexes Constructed from 1,4‐Bis[2‐(5‐phenyloxazolyl)]benzene

“…In addition, the design and synthesis of novel coordination architectures controlled by varying the reaction conditions (including temperature, [18,19] metal/ligand ratio, [20] pH, [21] solvents, [22] and counter anions [23,24] ) are of great interest in coordination chemistry and reactions. Appropriate control of the reaction conditions makes it possible to construct new materials with useful properties.…”

“…E63, m3013-m3014 [doi:10.1107 The self-assembly of metal-organic coordination polymers has attracted a great attention because of their potential as functional materials (Millward & Yaghi, 2005;Wong-Foy et al, 2006). When flexible ligands are involved in supramolecular architectures, the prediction of the topology of the coordination polymer is more difficult because there are several factors affecting the framework formation, such as the type of solvent, the counter-anion, and the metal-toligand ratio among others (Withersby et al, 1999(Withersby et al, , 1997Noro et al, 2002;Black et al, 1995;Blake et al, 1999;Bu et al, 2002;Carlucci et al, 2002). Neverthless, in order to gain more information about those subtle factors, not yet well understood, we have studied the effect of one parameter at a time on the topology of the networks (Awaleh et al, 2006a,b;.…”
