Breaking the trigonal host packing motif of Dianin's compound

Abstract

Crystallisation of Dianin's compound (DC) together with two organic amines (piperazine and piperidine) produces co-crystals of 2:1 DC-piperazine and 1:1 DC-piperidine, respectively. The structures of these adducts contrast sharply with that of the well-known clathrate structure of DC in which organic guests are generally included in ratios of 3:1 or 6:1 DC-guest. © The Royal Society of Chemistry 2009.</p
