characterization and crystal structures of four designed host-guest compounds of the compositions [Cu II L 1 } 2 ⊂(H 3 N(ethylene)NH 3 )](NO 3 ) 2 (1), [Cu II L 1 } 2 ⊂(H 3 N-(propylene)NH 3 )](NO 3 ) 2 (2), [Cu II L 1 } 2 ⊂(H 3 N(butylene)-NH 3 )](NO 3 ) 2 (3) and [Cu II L 2 } 2 ⊂(H 3 N(ethylene)NH 3 )](NO 3 ) 2 (4) are described in this investigation [H 2 L 1 = N,N'-ethylenebis(3-methoxysalicylaldimine);
Design of weak interaction directed self-assemblies of nickel(II) complexes using diprotonated diamines as supramolecular tectons: Syntheses and crystal structures
this paper reports syntheses, characterization and crystalstructures of three designed host–guest compounds [(NiIIL)2 ⊂ (H3NCH2CH2NH3)](NO3)2 (1), [(NiIIL)2 ⊂ (H3NCH2CH2CH2NH3)](NO3)2 (2) and [(NiIIL)2 ⊂ (H3NCH2CH2CH2CH2NH3)](NO3)2 (3), where H2L is the compartmental Schiff base ligand N,N′-ethylenebis(3-ethoxysalicylaldimine). All threecrystals are triclinic, compounds 1 and 3 are centrosymmetric
Noncovalent interactions have been studied with the use of experimental (potentiometric and spectroscopic measurements) and computational (molecular modeling and DFT) studies in a lysine, 1,3-diaminopropane and adenosine-5′-triphosphate system. The preferred coordination modes and possible structures of complexes of two obtained species (Lys)H4(tn)(ATP) and (Lys)H3(tn)(ATP) have been determined. Interestingly
