Ligand mediated structural diversity and role of different weak interactions in molecular self-assembly of a series of copper(II)–sodium(I) Schiff-base heterometallic complexes

Stacking interactions of resonance-assisted hydrogen-bridged rings and C6-aromatic rings

“…The stacking interactions are mainly connected with aromatic molecules, [1][2][3][4][5][6][7][8][9][10] however it was shown that various rings can form stacking interactions; aliphatic saturated [11][12][13][14][15][16] and unsaturated molecules, 17,18 metal-chelate rings, [19][20][21][22][23][24][25][26][27][28][29][30][31][32][33][34][35][36][37][38] and hydrogen-bridged rings. [39][40][41][42] 2D materials can also form stacking interactions.…”

Homo- and Hetero-Oligonuclear Complexes of Platinum Group Metals (PGM) Coordinated by Imine Schiff Base Ligands

“…The SB ligands were also studied in the macrocyclic forms of multidentate aza, oxoaza or thiaaza heterocyclic compounds [16] or oligo-and oligometalloporphyrins [99]. Additionally, the tautomerism of SBs and possibility of hydrogen bond or stacking interaction formation was studied intensively together with layer-by-layer (LbL) assembly for many applications [100][101][102][103][104][105][106][107][108].…”

Crystal structure of 2-ethoxy-6-((E)-((3-(((E)-3-ethoxy-2-hydroxybenzylidene)amino)-2-hydroxypropyl)iminio)methyl)phenolate, C21H26N2O5

“…There are several complexes containing the deprotonated title molecule as an anionic ligand, which have been reported, however, the structure about this ligand has not been reported [4][5][6]. The compound crystallizes in the monoclinic space group P21/c with four formula units in the unit cell.…”
