Hydrothermal Synthesis and Crystal Structure of a Novel Coordination Polymer[Co(pda)_2(H_2O)_2]_n

A novel coordination polymer[Co(pda)_2(H_2O)_2]_n was synthesized by hydrothermal reaction of CoCl_2·6H_2O 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)nm~3,Z=4,d_c=1.619g/cm~3,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.
