Noncovalent interactions in the design of bis-azo dyes

Abstract

A perfluorinated aromatic link was used as a synthon in the design of bis-azo dyes.

The Isocyanide Complexes cis-[MCl2(CNC6H4-4-X)2] (M = Pd, Pt; X = Cl, Br) as Tectons in Crystal Engineering Involving Halogen Bonds

“…Strategies of crystal engineering towards the design of solids with controllable structure and tunable physicochemical properties are amongst the well-recognized tools for material chemistry [1][2][3][4][5]. The emergence of halogen bonding (HaB; for reviews on HaB see references [6][7][8][9][10]) during the construction of supramolecular aggregates opens up a route for the optimisation of their valuable properties, such as catalytic activity [11][12][13][14][15], solubility [16,17], melting point [18], thermal expansion [19][20][21][22], colour [23][24][25][26][27], luminescence [28][29][30][31][32][33][34][35][36][37][38][39][40][41], sensing [42,43], biological [44], and magnetic [45] properties. Various tectons [46], including organic species or metal complex...…”

Crystal structure and Hirshfeld surface analysis of dimethyl 5-[2-(2,4,6-trioxo-1,3-diazinan-5-ylidene)hydrazin-1-yl]benzene-1,3-dicarboxylate 0.224-hydrate

“…The use of multifunctional ligands in coordination chemistry is a common way to increase the water solubility of metal complexes, which is important for catalytic applications in aqueous medium (Ma et al, 2020(Ma et al, , 2021Mahmudov et al, 2013;Sutradhar et al, 2015Sutradhar et al, , 2016. Moreover, non-covalent interactions such as hydrogen, halogen and chalcogen bonds as well as -interactions or their cooperation are able to contribute to synthesis and catalysis and improve the properties of materials (Gurbanov et al, 2020b;Karmakar et al, 2017;Khalilov et al, 2018a,b;Mac Leod et al, 2012;Shikhaliyev et al, 2019;Shixaliyev et al, 2014). For that, the main skeleton of the hydrazone ligand should be decorated by non-covalent bond donor centre(s).…”

Crystal structure and Hirshfeld surface analysis of (3aR,4S,7S,7aS)-4,5,6,7,8,8-hexachloro-2-{6-[(3aR,4R,7R,7aS)-4,5,6,7,8,8-hexachloro-1,3-dioxo-1,3,3a,4,7,7a-hexahydro-2H-4,7-methanoisoindol-2-yl]hexyl}-3a,4,7,7a-tetrahydro-1H-4,7-methanoisoindole-1,3(2H)-dione

“…On the other hand, N-heterocycles or N-ligands can also be used as precursors in the synthesis of coordination compounds (Ma et al, 2020(Ma et al, , 2021Mahmudov et al, 2013), and as building blocks in the construction of supramolecular structures as they have both hydrogen-bond donor and acceptor capabilities (Gurbanov et al, 2020a;Kopylovich et al, 2011a,b;Asgarova et al, 2019). In fact, attachment of suitable functional groups to N-ligands can improve their solubility and the catalytic activity of the corresponding coordination compounds (Mizar et al, 2012;Gurbanov et al, 2020b;Khalilov et al, 2011Khalilov et al, , 2018aMaharramov et al, 2019;Shikhaliyev et al, 2019;Shixaliyev et al, 2014). Intermolecular halogen bonds and other types of non-covalent interactions in halogenated N-heterocyclic compounds can improve their solubility and other functional properties.…”
