An open and flexible robotic system designed towards autonomous protein crystal harvesting

Abstract

Poster Sessions lattices and establishes that indeed fluorine has a directing influence in molecular assembly. In order to evaluate the propensity of interactions in halogens in general ortho chloro and ortho bromo anilines were crystallized from their respective liquids via in situ cryocrystallization method. The crystal structures are isostructural belonging to a trigonal system, space group P 31. The crystal packing is due to intramolecular N-H...Cl or Br and intermolecular N-H...N hydrogen bonds. However, in the case of ortho bromo aninline short Br...Br contacts (3.64 Å) are observed suggesting that this interaction is a consequence of the size of Br atom.
