Syntheses and Characterization of Two Cd(II) Coordination Polymers Based on Mixed Flexible Ligands

Abstract

Two new Cd(II) coordination polymers based on mixed flexible ligands, namely, {[Cd(dtsa)(bbi)]ÁDMF} n (1) and [Cd(dtsa)(bpp)] n (2) (H 2 dtsa = 2, 2 0 -dithiosalicylic acid, bbi = 1,1 0 -(1,4-butanediyl)bis(imidazole), bpp = 1,3-bi(4-pyridyl)propane), have been successfully constructed under solvothermal conditions. Complex 1 diplays a parallel threefold interpenetrating 2D layers with sql topology, and complex 2 is a 3D threefold interpenetrating architecture with bcu-x-4-P3212 topology. The photoluminescent spectra indicate that at room temperature, complexes 1 and 2 emit blue-purple luminescence.

Biporous Cd(II) Coordination Polymer via in Situ Disulfide Bond Formation: Self-Healing and Application to Photosensitive Optoelectronic Device

“…The S–S bond formation of 2-mercaptobenzoic acid (2-MBAH), which is assembled in a long flexible ligand 2,2′-disulfanediyldibenzoic acid (2,2′-DSBA), fabricates a large structural unit in the CPs of Cd­(II) as an ion node. − Herein we have employed the “ in situ ligand generation” technique of 2,2′-DSBA and INH links to construct Cd-based two-dimensional coordination polymer (2D CP) [Cd 2 (2,2′-DSB) 2 (INH) 2 (H 2 O) 2 ] n ( 1 ) (2,2′-disulfanediyldibenzoic acid (2,2′-DSBA) and isonicotinohydrazide (INH)) (Scheme ). In recent times, in situ ligand generation has grown to be an attractive synthetic pathway to harvest novel coordination polymers.…”
