Molecular architecture using novel types of non-covalent π-interactions involving aromatic neutrals, aromatic cations and π-anions

Experimental and Computational Study of Counterintuitive ClO4–···ClO4– Interactions and the Interplay between π+–π and Anion···π+ Interactions

“…Both experimental and theoretical evidence of interesting synergetic effects between anion-π and HB and between anion-π and π−π stacking interactions has been reported recently which displays that the interplay between these interactions can direct to strong cooperativity effects. [29][30][31][32][33][34][35][36][37][38][39][40] Recently, experimental evidence of anion-π-π interactions has emerged from crystallographic studies [41][42][43][44] on synthesized compounds based on the electron-deficient pyridine moieties, suggesting the possibility to enhance anion-π binding by π-π stacking. In the present study, we investigate and explore the structural features of this anion-π-π complex, and the energetic associated to anion-π, π + -π + and π + -π interactions using a combination of single crystal X-ray diffraction and density 3 functional theory (DFT) calculations.…”

Synthesis, characterization and crystal structure determination of Mn (II) ion based 1D polymer constructed from 2, 2′ bipyridyl and azide group, its thermal stability, magnetic properties and Hirshfeld surface analysis

“…The Mn…Mn distance through end to end bridging of azide is 5.408 Å and end-on bridging of azide is 3.399 Å. The end to end bridging azides and end-on bridging azides are quasi perpendicular to This complex is associated through π-π and CH-π interactions which organizes it into hydrogen bonded supramolecular network and responsible for strengthening of molecular assembly [32][33][34].…”

Pd(II)–N-heterocyclic carbene complexes of annelated ligand: Synthesis, characterization, and catalytic activity

“…The molecule possesses several C-HÁ Á Áp, C-HÁ Á ÁF, and anionÁ Á Áp interactions (shown in Fig. 4) and that are relevant to other reported systems [46][47][48].…”
