Edge-directed assembly of a 3D 2p–3d heterometallic metal–organic framework based on a cubic Co8(TzDC)12 cage

Abstract

A three-dimensional (3D) heterometallic metal–organic framework containing cubic-like cages, namely {[Co3Na6(TzDC)4(H2O)6]·7H2O}n (1) (H3TzDC = 1,2,3-triazole-4,5-dicarboxylate), has been synthesized by the edge-directed self-assembly of TzDC3−, Co2+ and Na+ ions. Crystal data reveals that one hydrous Co2+ cation is embedded in the central cavity of a cubic-like cage [Co8(TzDC)12]20− with eight Co2+ cations as the corners and twelve TzDC3− ligands as the edges. The cages are further bridged by Na+ ions to result in a 3D framework with pcu topology. Magnetic investigation indicates that besides the spin–orbit coupling of Co2+ ions, an antiferromagnetic exchange interaction was found to exist between the Co2+ ions in the Co9 cluster of 1.
