【摘要】 以CoC l2.6H2O和3-(3-吡啶基)丙烯酸(pda)为原料,在中温水热反应条件下,合成了一种新型配位聚合物[Co(pda)2(H2O)2]n单晶体,并对其进行了元素分析、红外光谱表征、TGA-GTA分析和X射线单晶衍射测定。该配位聚合物属单斜晶系,P2(1)/c空间群,晶胞参数为a=1.6958(8)nm;b=0.5466(3)nm;c=1.8034(8)nm;α=90°;β=106.209(7);°γ=90;°M r=391.24;V=1.6051(13)nm3;Z=4;dc=1.619g/cm3;μ=1.106mm-1;F(000)=804;R1=0.0367;wR2=0.0711。该晶体通过配位键的连接形成二维结构,又通过分子间氢键和π-π相互作用形成三维的网状结构。更多还原

【Abstract】 A novel coordination polymer[Co（pda）₂（H₂O）₂]_n was synthesized by hydrothermal reaction of CoCl₂·6H₂O and 3-（3-pyridyl） acrylate acid.The structure was characterized by elemental analysis and IR spectroscopy as well as TGA-GTA analysis and X-ray single crystal diffractometer.The analysis reveals the crystal in the monoclinic crystal system and P2（1）/c space group,with crystallographic data: a=（1.6958（8）nm,） b=0.5466（3）nm,c=1.8034（8）nm,α= 90°,β=106.209（7）°,γ= 90°,V=（1.6051）（13）nm³,Z=4,d_c=1.619g/cm³,μ=1.106mm^-1,F（000）=804,R1=0.0367 and wR2=（0.0711）.X-ray analysis reveals that a three-dimensional interpenetrating net was formed by hydrogen bonds and π-π bonds.更多还原
