Self-assembly
of Cd(NO3)2 with a new C
2-symmetric multidentate N-donor ligand, N,N′-((1,1′-(anthracene-9,10-diylbis(methylene))bis(1H-1,2,3-triazole-4,1-diyl))bis(methylene))bis(1-(pyridin-3-yl)-N-(pyridin-3-ylmethyl)methanamine) (L), gives rise to crystals
of two-dimensional (2D) frameworks (sql), 4C4H8O2@[Cd(NO3)2L], with available interlayer
open space occupied by solvate 1,4-dioxane molecules. The interlayer
distance between the 2D frameworks can be modulated via adsorption
of various cyclic hydrocarbons in the single-crystal to single-crystal
mode. In this mode, the 1,4-dioxane solvate molecules were, in the
present study, replaced for adsorption of benzene, 1,4-dioxane, anisole, trans-decalin, 1,4-benzodioxane, and 1,5-cyclooctadiene.
This crystal system, furthermore, could be useful as an efficient
and tolerant crystalline matrix for molecular-structure determination
of a wide range of cyclic hydrocarbons.
