Two novel 3D porous Copper(II) and Zinc(II) frameworks with 1,3-di-(1,2,4- triazole-4-yl)benzene: 4-connected dmp network versus 6-connnected α-Po network based on trinuclear Zinc(II) clusters

Used versatile multidentate benzene-based bis-triazole ligand 1,3-di-(1,2,4-triazole-4-yl)benzene (L), two novel 3D porous Copper(II) and Zinc(II) frameworks, namely {[Cu(μ2-L)2(SiF6)(H2O)]·0.5H2O}n (1) and {[Zn3(μ3-L)6](NO3)6}n (2), have been isolated under the hydrothermal conditions. The structural analysis reveals that 1 presents a 3D microporous Copper(II) framework with the novel 4-connected 6383 dmp topology containing infinite right- and left-handed Cu(μ2-L)2 helical chains. While 2 presents a 3D cluster-based nano-porous cationic host framework with 6-connected α-Po-related (41263) topology, in which trinuclear Zinc(II) clusters can be defined as basic nodes. The varied temperature magnetic susceptibility of 1 (from 300 to 2 K) and solid state luminescent property of 2 also have been investigated.
