| Abstract: | The hydrothermal self-assemblies of Pb2+/Cd2+ salt, 4,5-dichlorophthalic acid (dcpha), N2H4·H2O together with 1,10-phenanthroline·H2O (phen) or 2,2′-bipyridine (bpy) generated two new monoacylhydrazidate-bridged 1-D chained coordination polymers Pb2(DCPTH)4(phen)2] 1 and Cd3(DCPTH)2(dcph)2(bpy)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 N2H4·H2O. 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. |
