Title: Synthesis,Crystal Structure and Properties of a New Zn(II) Coordination Polymer Constructed Based on 4-( 1H-Pyrazol-3-yl) Pyridine
Abstract: A new Zn( II) coordination polymer,[Zn3( 4-PP)4( OH)2( SO4)2( H2O)2]n( 1,4-PP = 4-( 1H-pyrazol-3-yl) pyridine),had been synthesized by hydrothermal method and structurally characterized by single-crystal X-ray diffraction as well as elemental analysis,IR spectra,PXRD,TG,and the thermal and fluorescent properties of the compound were also investigated. Compound 1 crystallizes in monclinic space group P21/ c,with a = 12. 303( 3) nm,b = 6. 0083( 12) nm,c = 25. 308( 5) nm,β = 101. 40( 3) °,F( 000) = 1056,Dc= 1. 882 g / cm3,V = 1833. 8( 6) nm3,Mr= 1038. 94,Z = 2,μ( Mo Kα) =2. 140 mm-1,R1= 0. 0672,wR2= 0. 1300. In the complex 1,Zn( II) ion bridged by SO2-4and OH-to construct a two-dimensional inorganic layer structure,and 4-PP ligand serves as the terminal ligand. The two-dimensional layers are assembled into three-dimensional supramolecular structures through the hydrogen bonding interactions.( CCDC: 1007042)
