Resumen

WAHL, Helene; HAYNES, Delia A.  y  ROEX, Tanya le. Lack of Co-crystal Formation with Cyclotriphosphazenes: A Cautionary Tale. S.Afr.j.chem. (Online) [online]. 2016, vol.69, pp.35-43. ISSN 1996-840X.  http://dx.doi.org/10.17159/0379-4350/2016/v69a5.

The attempted formation of co-crystals with a series of cyclotriphosphazene derivatives has been investigated. Despite numerous attempts, only one co-crystal was obtained. The crystal structure of this material, [hexakis(4-pyridyloxy)-cyclotriphos-phazene][terephthalic acid]2y is presented here. The crystal structures of 2,2-bis(4-formylphenoxy)-4,4,6,6-bis[spiro(2',2"-dioxy-1',1"-biphenylyl]cyclo-triphosphazene and hexakis(4-cyanophenoxy)cyclotriphosphazene are also reported for the first time. The extremely low rate of co-crystal occurrence in these materials cannot be explained, despite the consideration of several possibilities. This serves as a cautionary tale - co-crystal formation is not necessarily straightforward.

Palabras clave : Cyclophosphazene; lack of co-crystal formation.
