High and selective sorption of C2 hydrocarbons in heterometal–organic frameworks built from tetrahedral units†
Abstract
Alternate connection of tetrahedral [In(COO)4]− and [AgN4]+ (or [CuN4]+) units via nicotinate ligands leads to the formation of two metal–organic frameworks (MOFs) based on packing layers. The activated framework shows high C2 hydrocarbons (C2s) uptake and high selectivities of C2s/CH4.
