Abstract
Hydrothermal reaction of Sr(II) salt with the promising multifunctional organic ligand, 2-(3,4-methylenedioxyphenyl)-1 H -imidazole-4,5-dicarboxylic acid (MDPhH 3 IDC), leads to one new Sr(II) polymer, namely [Sr(MDPhH 2 IDC) 2 (H 2 O) 3 ] n ( 1 ), which has been structurally characterized by elemental analysis, IR spectrum, and single crystal X-ray diffraction analysis. In polymer 1 , the Sr(II) atoms are linked by water ligands to develop many 1-D chains. These chains are further joined by the MDPhH 2 IDC − ligands to build up a fascinating 3-D structure. Interestingly, the polymer contains many dinuclear Sr(II) clusters as secondary building blocks. The thermal and photoluminescence properties of the polymer have been investigated as well. One Sr(II) polymer has been successfully isolated from the reaction of 2-(3,4-methylenedioxyphenyl)-1 H -imidazole-4,5-dicarboxylic acid (MDPhH 3 IDC) with equal amount of Sr(II) salt under hydrothermal condition. It has been structurally characterized by elemental analysis, IR spectroscopy and single-crystal X-ray diffraction. • One 3D Sr polymer has been isolated. • 3,4-methylenedioxyphenyl imidazole dicarboxylate hydrothermally reacts with Sr ion. • The polymer has structurally characterized. • The thermal and photoluminescence properties of the polymer have been determined.
