A chiral porous 3D metal–organic framework with an unprecedented 4-connected network topology†
Abstract
A novel homochiral 3D metal–organic framework [CdL2(H2O)2][ClO4]2·2DMF·3EtOH·5/3H2O, 1, (L =
(R)-6,6′-dichloro-2,2′-diethoxy-1,1′-binaphthyl-4,4′-bipyridine) exhibits an unprecedented 4-connected network topology owing to the cis- configuration of the Cd coordination and possesses permanent porosity as demonstrated by
