Copper(I) π-complexes with allyl derivatives of heterocyclic compounds: structural survey of their crystal engineering

Abstract

In this review an exhaustive crystallochemical analysis of copper(I) π-complexes with allyl derivatives of heterocyclic compounds has been performed. Structural genesis of inorganic constituents starting from the simplest units to the most complicated aggregates was considered taking into account the specific role of Cu-(C=C) interaction, the construction of the organic ligands, the basicity and nucleophilic activity of their heteroatoms, as well as olefin Cu(I) π-complex preparation route.

Copper(I) chloride and copper(I) perchlorate π-complexes with 2-allylthio-5-methyl-1,3,4-thiadiazole: synthesis and crystal structure

“…Отже, два атоми купруму координуються з трьома молекулами органічного ліганду, при чому дві з них є π,σ-координованими містково-хелатним способом, а третя лише поєднує два металічні центри атомами нітрогену гетероциклічного ядра. На відміну від більшості досліджених раніше π-комплексів купруму(І) з алільними похідними гетероциклічних сполук, у яких перхлорат-аніон є координованим до атома металу [21], в структурі 2 утворені катіони [Cu2(Almethia)3] 2+ і аніони ClO4поєднані виключно електростатичними взаємодіями.…”

A new tetranuclear copper(I) complex based on allyl(5-phenyl-1,3,4-thiadiazol-2-yl)azanide ligand: Synthesis and structural characterization

“…Polynuclear transition metal complexes are very attractive objects from the view point of their potential applications in catalysis, medicine and physics as well as for their original role in the crystal structure engineering of the metal-organic frameworks [1][2][3][4][5][6][7][8]. A specific attention of researchers has been paid for the synthesis and investigation of multinuclear metal clusters in which the specific interactions between closely spaced transition metal centers are believed to play an important role in crucial change of physical properties and reactivities.…”

Ligand-forced dimerization of copper(I)–olefin complexes bearing a 1,3,4-thiadiazole core

“…In recent years, specific attention have been paid to the investigation of copper(I) -complexes with allyl derivatives of heterocyclic compounds, since the simultaneous presence of a heterocyclic core and an allylic radical bonded to them plays an important role in the formation of unusual inorganic fragments (Slyvka et al, 2013). The contribution from the -dative (Cu!C C) -component of a Cu I -olefin bond to the tetrahedral ligand field leads to a splitting of the copperion d orbitals and brings about a considerable deformation of the initial tetrahedral copper(I) environment to trigonal pyramidal.…”
