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

Abstract

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(μ 2 -L) 2 (SiF 6 )(H 2 O)]·0.5H 2 O} n ( 1 ) and {[Zn 3 (μ 3 -L) 6 ](NO 3 ) 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 6 3 8 3 dmp topology containing infinite right- and left-handed Cu(μ 2 -L) 2 helical chains. While 2 presents a 3D cluster-based nano-porous cationic host framework with 6-connected α-Po-related (4 12 6 3 ) 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. Two novel 3D porous frameworks with 1,3-di-(1,2,4-triazole-4-yl)benzene have been isolated. 1 presents a 3D microporous Cu(II) framework with 4-connected 6383 dmp topology, while 2 presents a 3D cluster-based nano-porous framework with 6-connected α-Po-related topology. • Two novel 3D porous Copper(II) and Zinc(II) frameworks have been isolated. • 1 presents a 3D Copper(II) framework with 4-connected 6383 dmp topology. • 2 presents a 3D cluster-based framework with 6-connected α-Po-related (41263) topology.
