Co-crystal of suberic acid and 1,2-bis(4-pyridyl)ethane: A new case of packing polymorphism 2017 Access copy available to the general public Unrestricted The polymorphic behaviour of a co-crystal composed of neutral suberic acid and 1, 2-bis(4-pyridyl)ethane is reported. A multidisciplinary approach has been employed, using thermal analysis methods (differential scanning calorimetry and polarized light thermomicroscopy), spectroscopic methods (infrared spectroscopy) and X-ray single crystal and powder diffraction. Two new polymorphs, I and III; have been identified, and for one of them the crystal structure has been elucidated and compared to that of a known polymorph, form II, showing that the assembling of the molecules in chains via H-bonds is a common feature of both polymorphs. Polymorph II, obtained by crystallization from an aqueous or ethanol solution or by grinding, undergoes a solid-solid transition to polymorph I, which melts at 180.5 °C. Upon cooling from the melt, polymorph I is obtained, and a solid-solid transformation also occurs, to polymorph III''. Polymorph III was obtained serendipitously in an attempt to prepare a Nd(III) complex. The relative stability of the three polymorphic forms was established. info:eu-repo/semantics/openAccess by-nc-nd http://creativecommons.org/licenses/by-nc-nd/3.0/es/ 2.011 2017 CHEMISTRY, PHYSICAL 86 / 146 = 0.589 2017 Q3 T2 0.409 2017 Analytical Chemistry 2017 Q3 Spectroscopy 2017 Q3 Organic Chemistry 2017 Q3 Inorganic Chemistry 2017 Q3 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion (orcid)0000-0003-2713-2786 Martín-Ramos, Pablo Universidad de Zaragoza Maria, Teresa M.R.
