Cocrystallization of the widely used model pharmaceutical compound (caffeine), with an array of organic acids gave five anhydrous and hydrous multicomponent adducts (1,3,7-trimethyl-3,7-dihydro-purine-2,6‑dione): (4-chlorophenoxyacetic acid) [(L) · (Hcpa), Hcpa = 4-chlorophenoxyacetic acid] (1), (1,3,7-trimethyl-3,7-dihydro-purine-2,6‑dione)2: ((2,4-dichlorphenoxy)acetic acid) [(L)2 · (Hdcpa), Hdcpa = (2
广泛使用的模型药物化合物(咖啡因)与一系列有机酸共结晶得到五种无水和含水多组分加合物(1,3,7-三甲基-3,7-二氢-嘌呤-2,6-二酮):( 4-氯苯氧乙酸)[(L)·(Hcpa),Hcpa = 4-氯苯氧乙酸](1),(1,3,7-三甲基-3,7-二氢嘌呤-2,6-二酮)2: ((2,4-二氯苯氧基)乙酸) [(L) 2 · (Hdcpa), Hdcpa = (2,4-二氯苯氧基)乙酸] (2) , (1,3,7-trimethyl-3,7- dihydro-purine-2,6-dione) 3 : (2-hydroxy-5-(phenyldiazenyl)benzoic acid) 2 [(L) 3 · (Hpba) 2 , Hpba = 2-hydroxy-5-(phenyldiazenyl)benzoic acid ] ( 3), (1,3,7-trimethyl-3,7-dihydro-purine-2
