Abstract

By treating FeSO4 or Mn(OAc)2 with 5′-(pyridin-2-yl)-2H,4′H-3,3′-bi(1,2,4-triazole) (H2pbt), three novel metallamacrocycle-based complexes [Fe(Hpbt)(C2O4)0.5]n (1), {[Fe(pbt)(H2O)]·2H2O}n (2), {[Mn(pbt)(H2O)]·2EtOH·0.5H2O}n (3) have been synthesized and characterized. In 1, the hexanuclear metallamacrocycle units are connected with each other resulting in the formation of two-dimensional frameworks. Octanuclear metallamacrocycle-based complexes 2 and 3 display three-dimensional porous frameworks. Interestingly, left- and right-handed helical chains present alternately along the crystallographic c axis in 2 and 3. Magnetic susceptibility measurements show that the three complexes display different antiferromagnetic coupling intensities.
