摘要：
A cocrystal of caffeine (cat) and 2-hydroxy-1-naphthoic acid (2H1NA), namely, (cat) (2H1NA), was discovered via a screening method based on solution-mediated phase transformation (SMPT) The components crystallize as a two-component hydrogen-bonded assembly involving both an intermolecular O-H N and intramolecular O-H O hydrogen bond The assemblies stack parallel and offset Crystal data monoclinic P 2(1)/n space group, a = 7 909(2) A, b = 15 275(5) A, c = 14 704(5) A, beta = 103 66(1)degrees, Z = 4, V = 1726 1(9) A(3), D(c) = 1 471 g/cm(3) and R(1) = 0 081, wR(2) = 0 163 The cocrystal (cat) (2H1NA) was also subjected to polymorph screening using 15 different solvents, with all resulting solids being identified as the original form
