Capture of volatile iodine by newly prepared and characterized non-porous [CuI]n-based coordination polymers / T. A., N. V., B. E., L. Carlucci, D.M. Proserpio. - In: CRYSTENGCOMM. - ISSN 1466-8033. - 19:41(2017), pp. 6116-6126. [10.1039/C7CE01193H]
Abstract:
Four new non-porous CuI-coordination polymers [Cu-2(mu(3)-I)(2)(mu-bpb)](n) (1a), [Cu(mu(2)-I)(mu-bpb)](n) (1b), [Cu-4(mu(2)-I)(4)(mu-bpmb)(4)](n) (2), and [CuI(mu-bdb)](n) (3) (bpb = 1,4-bis(pyrazolyl) butane; bpmb = 1,4-bis[(pyrazolyl)methyl]benzene; bdb = 1,4-bis[(3,5-dimethylpyrazolyl)methyl] benzene) have been successfully prepared and their structures fully characterized by single-crystal X-ray diffraction, FT-IR spectroscopy, PXRD and elemental analysis. Crystallographic investigation revealed that 1a, 1b, and 2 exhibit two-dimensional (2D) structures; in 1a parallel [Cu2I2](n) staircase motifs are cross-linked into two-dimensional sheets by bpb linkers with a fully extended conformation, while in the structures of 1b and 2 Cu2I2 rhomboid dimers are linked by bpb and pbmb ligands, respectively, into two-dimensional sheets with a 4(4)-sql net. Differently, compound 3 shows a one-dimensional (1D) zigzag chain structure with monomeric CuI units. All the four non-porous coordination polymers show the ability to capture volatile iodine in the gas phase. The solid-state photoluminescence properties of 1a, 1b, and 2 have also been investigated. The iodine-adsorbed samples 1a-I-2, 1b-I-2, and 2-I-2 show no fluorescence behavior.
