Abstract
- The hydrothermal self-assemblies of Pb{sup 2+}/Cd{sup 2+} salt, 4,5-dichlorophthalic acid (dcpha), N{sub 2}H{sub 4}.H{sub 2}O together with 1,10-phenanthroline.H{sub 2}O (phen) or 2,2'-bipyridine (bpy) generated two new monoacylhydrazidate-bridged 1-D chained coordination polymers [Pb{sub 2}(DCPTH){sub 4}(phen){sub 2}] 1 and [Cd{sub 3}(DCPTH){sub 2}(dcph){sub 2}(bpy){sub 2}] 2 (DCPTH=4,5-dichlorophthalhydrazidate, dcph=4,5-dichlorophthalate). The monoacylhydrazidate ligand DCPTH originated from the hydrothermal in situ acylation reaction between dcpha and N{sub 2}H{sub 4}.H{sub 2}O. In compound 1, two types of coordination modes for DCPTH are found, which link alternately the Pb(II) centers into a 1-D chain structure of compound 1 with ancillary phen molecules. In compound 2, DCPTH and dcph as the mixed bridges extend the Cd(II) centers into a 1-D chain structure of compound 2 with auxiliary bpy molecules. DCPTH in compound 2 shows a different coordination mode from those observed in compound 1. -- Graphical abstract: By applying the in situ acylation reaction between 4,5-diclorophthalic acid and N{sub 2}H{sub 4}.H{sub 2}O, two 4,5-dichlorophthalhydrazidate-bridged chained compounds [Pb{sub 2}(DCPTH){sub 4}(phen){sub 2}] and [Cd{sub 3}(DCPTH){sub 2}(dcph){sub 2}(bpy){sub 2}] (4,5-dichlorophthalhydrazidate=DCPTH, and dcph=4,5-dichlorophthalate) were hydrothermally synthesized. Display Omitted Research highlights: > In this article, we first reported the preparations and structural characterization of two examples of 4,5-dichlorophthalhydrazidate-bridged chained coordination polymers [Pb{sub 2}(DCPTH){sub 4}(phen){submore » 2}] 1 and [Cd{sub 3}(DCPTH){sub 2}(dcph){sub 2}(bpy){sub 2}] 2. 4,5-dichlorophthalhydrazidate derived from the hydrothermal in situ acylation reactions between 4,5-dichlorophthalic acid and N{sub 2}H{sub 4}.H{sub 2}O. > In this article, a simple method to judge whether the polycarboxylic acid precursors have acylated into the acylhydrazidate ligands is introduced. > In this article, DFT calculations were carried out on the excited electronic states of the compounds, the fluorescence emission properties of the compounds have been better understood. > this article, by the structural characterization of the obtained monoacylhydrazidate-containing compounds, the character of the monoacylhydrazidate ligands has been further understood.« less
