Popis:	In the paper, a series of new pillar-layered supramolecular complexes have been built up through second-sphere coordination. Three N,N,N′,N′-tetrabenzyl diamine ligands [N,N,N′,N′-tetrabenzyl-ethylenediamine (L1), N,N,N′,N′-tetrabenzyl-2-butyne-1,4-diamine (L2) and N,N,N′,N′-tetrabenzyl-(p-xylylene)-diamine (L3)] were synthesised, and can react with [Fe(CN)6]3 via second-sphere coordination, yielding pillar-layered supramolecular complexes, [H2L1]0.5·[Fe(CN)6]0.5 ⊃ 0.5H3O·1.5H2O (Crystal 1), [H2L2]0.25·[Fe(CN)6]0.25 ⊃ 0.5H3O·0.5H2O (Crystal 2) and [H2L3]·[Fe(CN)6] ⊃ Cl·ethylene glycol·H2O (Crystal 3). The 3D networks are organic layers formed by the self-assembly of the ligands through extensive hydrogen-bonding interactions (π…π stacking or C–H…π interactions) and further interconnected by [Fe(CN)6]3 − in a pillar fashion, constructing into pillar-layered networks with channels accessible to various guest molecules. The inclusion property of [H2L1]·[Fe(CN)6] was studied; varieties of guest molecules, su...
