title: Separation/purification of ethylene from an acetylene/ethylene mixture in a pillared-layer porous metal-organic framework.
abstract: Here we report the synthesis, structure and porous properties of a 3D pillared-layer porous framework of Mn(ii)-Mn(iii), {[Mn3(bipy)3(H2O)4][Mn(CN)6]2·2(bipy)·4H2O}n(1). The guest-removed framework (1a) shows significant uptake of C2H2, whereas it excludes the other two C2 hydrocarbons (C2H4and C2H6). Furthermore, excellent separation proficiency for C2H2from a mixture of C2H2and C2H4(1 : 99, v/v) is realized in a breakthrough column experiment under ambient conditions.
