Two solvent-dependent porous coordination polymers with –OH decorated ligands: unusual non-crystallographic net and fsh topology

Abstract

Two new porous coordination polymers (PCPs), ([Cu6(L)4·(H2O)6]·10DMA·4EtOH, (1) and [Cu5(L)2 (OH)2·(H2O)2·DMA2]·2DMA·EtOH·2H2O (2), were solvothermally synthesized and structurally characterized. Interestingly, their variable architectures controlled by solvent system exhibit a structural progression from an unusual non-crystallographic (NC) net to a (4,6)-connected framework with fsh topology. Moreover, the combination of 3D channels of about 3.0 × 7.2, 4.7 × 9.5, and 6.3 × 7.8 Å2, and functional –OH groups in 2′ lead to good selectivity of CO2 over CH4 (26-55 by IAST) at 273 K.
