摘要

The ongoing investigation of a copper (II) complexes has led to the development of novel hydrogen-bonded metal–organic frameworks (HBMOFs). In the present work, a copper (II) pyridine dicarboxylic acid, Cu(HPDCA)2(H2O)2, is reacted with phenethylamine to yield a lamellar framework featuring an octahedral geometry across the copper (II) center. The incorporation of phenethylamine results in an extended interlayer separation relative to previously reported HBMOFs. This layered architecture is capable of accomodating a range of guest molecules, including both alkyl and benzyl alcohols. Herein, we report the structutal characterizations of four guest-included hydrogen-bonded frameworks, compared against the corresponding guest-free framework: (1) [phenethylammonium]2Cu(PDCA)2(H2O)2, (2) [phenethylammonium]2Cu(PDCA)2(H2O)2·(1-pentanol), (3) [phenethylammonium]2Cu(PDCA)2(H2O)2·(1-hexanol), (4) [phenethylammonium]2Cu(PDCA)2(H2O)2·(benzyl alcohol), (5) [phenethylammonium]2Cu(PDCA)2(H2O)2·(4-chlorobenzylalcohol).
