By employing the same HT crystallization workflow developed for TMA, we screened 192 'good-bad' solvent' combinations, and 36 'good-good' solvent combinations for the crystallization of ADTA. Using the predicted 3-, 4-, and 5-fold structures as a reference (Table and Figure ) along with experimental X-ray diffraction data (SI, Tables ), we found that 5 sets of conditions led to new ADTA crystal forms with 3-fold interpenetrated diamondoid hydrogen bonded networks, 81 conditions led to 4-fold interpenetration, and 77 conditions led to 5-fold interpenetration (Figure ; SI, Figure ). We also identified 22 crystallizations that appeared to give a phase mixture of 4-and 5-fold interpenetrated structures (Figure ). The remaining conditions produced two amorphous samples, and 41 structures that could not be identified as one, or a mixture, of the 3-, 4-, or 5fold structures by simply comparing PXRD patterns (SI, Figure ).
