Abstract
Hydrothermal reactions of Zn(CH3COO)2·2H2O with two new triazine-based phosphonic acids, 2,4,6-triglyphosate-1,3,5-triazine (H9L1) and 4,6-biglyphosate-2-hydroxyl-1,3,5-triazine (H6L2), afforded two new zinc phosphonates, namely, [(C5H14N2)Zn3(HL1)(H2O)]·3.5H2O (1) and [(C5H14N2)Zn2L2]·3H2O (2), respectively. The two zinc phosphonates were structurally characterized through single-crystal X-ray diffraction. Compound 1 is a three-dimensional (3D) framework in that Zn–O–P chains are connected by HL18– anions with hendecadentate modes. In compound 2, each L26– anion links four Zn2 binuclear units to form a 3D framework. In both compounds 1 and 2, the protonated 2-methylpiperazines are encapsulated into the channels of 3D frameworks. Thermogravimetric analysis and powder X-ray diffraction reveal that compounds 1 and 2 are thermally stable up to 200 and 160 °C under an air atmosphere, respectively. Compounds 1 and 2 display near-UV and purple luminescence with maximal bands at 377 and 402 nm, respectively. It ...
