Interweaving of triple-helical and extended metal-O-metal single-helical chains with the same helix axis in a 3D metal-organic framework

Abstract

A novel 3D metal-organic framework [Cd2(m-bptc)(4,4′-bpy) 0.5(H2O)4]· H2O (1; m-H 4bptc = 1,1′-biphenyl-2,3′,3,4′-tetracarboxylic acid, 4,4′-bpy = 4,4′-bipyridine) with interweaving of triple- and single-helical chains has been obtained based on hydro(solvo)thermal reactions. © 2006 American Chemical Society.
