The heterocycle melamine appended to a 14-membered polyazamacrocyclic coppe
r(II) complex ring exhibits a strong propensity for ordered arrays driven b
y H-bonding forces. In this work, the X-ray crystal structures of three dis
tinctly different arrays based on the same macrocyclic complex are reported
, comprising cocrystals with barbituric acid (a sheet structure) and cyanur
ic acid (a linear chain) and the parent complex (a linear tape).
