Molecular Recognition: The Demonstration of 1,3-Bis[(pyrid-2-ylamino)carbonyl]adamantane as an Exceptionally Versatile Assembler of One-Dimensional Motifs

Syntheses and crystal structures of 1,3-bis[(pyrid-2-ylamino)carbonyl]adamantane ( 1 ) and its perchlorate salt, copper(II) complex, and 1:1 complexes with a large variety of simple and functionalized 1,ω-alkanedicarboxylic acids, HOOC−X−COOH [X = (CH 2 ) n, n = 2, 3, 5, and 8; −CH 2 −CO (α-ketoglutaric acid); CH CH (maleic acid)] are described. The molecule 1 exhibits remarkable adaptability with respect to the conformation of its two hydrogen-bonding subunits to suit the requirements of the assembling partners so as to generate persistently one-dimensional motifs, for example, infinite zig-zag ribbons with perchlorate ions and chains with both Cu(II) ions and dicarboxylic acids.
