Hydrothermal Synthesis and Structure characterization of two Hybrid Metal Phosphonates Materials

摘要

Under hydrothermal conditions, two copper phosphonates[Cu_2(H_2O)_2(H_2L)(bpy)_2(H_3L)_2]-2H_2O (1) and [Cu_2(H_2O)_2(H_2L)2(phen)_2]-6H_2O (2) (H4L = p-xylylenediphosphonic acid, bpy = 2,2'-bipyridine and phen = 1,10-phenanthroline), have been synthesized using diethyl p-xylylenediphosphonate (dixdp), in which p-xylylenediphosphonic acid (H4L) was generated via in situ hydrolysis. Complexe 1 forms a zero-dimensional (0D) bimetallic rings, while complex 2 features a 0D structure containing two kinds of partially deprotonated H_3L-and H_2L~(2-) ligand.
