The solid-state structure of the complex of para-sulfonatocalix[4]arene with d-arginine, contains a water channel diagonal to a zigzag bilayer of the host, within the bilayer six crystallographically independent molecules of arginine are present, four being included in the calix cavities.

MINT‐7266036: gamma CA2 (uniprotkb:Q9C6B3) and gamma CA2 (uniprotkb:Q9C6B3) physically interact (MI:0914) by molecular sieving (MI:0071)

1 - ArticleThe solid state structures of the complexes between antiseptic chlorhexidine and three anionic calix[4] arene derivatives are described. Each of the three calixarenes shows typical self-organisation in the solid-state that will further impose a specific complexation of the active molecule in the co-crystal

The calix[4]arene dihydroxyphosphonic acid-1,10-phenanthroline complex shows caging of the guest molecules as a pi-pi stacked dimer in a cavity formed by intermolecular hydrogen bonds and aromatic walls formed by the calixarene.
