In this paper the reasons for this peculiar behavior are investigated, employing a joint experimental and theoretical approach. This includes the design of cocrystals with coformers having a high propensity towards the formation of both aromatic\u2013aromatic and hydrogen-bonding interactions, determination of their structure, using solid-state NMR spectroscopy and X-ray crystallography, as well as calculations of stabilization energies of formation of the obtained cocrystals, followed by crystal structure prediction calculations and solubility measurements. The findings indicate that the stabilization energies of cocrystal formation are positive in all cases, which results from strain in the APR conformation in these crystal forms. On the other hand, solubility measurements show that the Gibbs free energy of formation of the apremilast:picolinamide cocrystal is negative, suggesting that the formation of the studied cocrystals is entropy driven. This entropic stabilization is associated with the disorder observed in almost all known cocrystals and solvates of APR.<\/jats:p>","DOI":"10.1107\/s205252061900917x","type":"journal-article","created":{"date-parts":[[2019,9,10]],"date-time":"2019-09-10T14:53:01Z","timestamp":1568127181000},"page":"803-814","update-policy":"https:\/\/doi.org\/10.1107\/cm_01","source":"Crossref","is-referenced-by-count":20,"title":["Understanding the formation of apremilast cocrystals"],"prefix":"10.1107","volume":"75","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3412-0177","authenticated-orcid":true,"given":"Marta K.","family":"Dudek","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5325-6072","authenticated-orcid":true,"given":"Ewelina","family":"Wielgus","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8601-3977","authenticated-orcid":true,"given":"Piotr","family":"Paluch","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2272-3691","authenticated-orcid":true,"given":"Justyna","family":"\u015aniechowska","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Maciej","family":"Kostrzewa","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8396-2771","authenticated-orcid":true,"given":"Graeme M.","family":"Day","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3787-7522","authenticated-orcid":true,"given":"Grzegorz D.","family":"Bujacz","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5672-0638","authenticated-orcid":true,"given":"Marek J.","family":"Potrzebowski","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"329","published-online":{"date-parts":[[2019,9,7]]},"reference":[{"key":"xk5057_bb1","doi-asserted-by":"crossref","first-page":"1054","DOI":"10.1039\/C5CE02234G","volume":"18","author":"Abraham","year":"2016","journal-title":"CrystEngComm"},{"key":"xk5057_bb2","doi-asserted-by":"crossref","first-page":"2863","DOI":"10.1039\/C9CE00124G","volume":"21","author":"Ahuja","year":"2019","journal-title":"CrystEngComm"},{"key":"xk5057_bb3","doi-asserted-by":"crossref","first-page":"17","DOI":"10.1016\/j.ssnmr.2013.11.001","volume":"57-58","author":"Althaus","year":"2014","journal-title":"Solid State Nucl.
