Abstract
Two coordination polymers,［Ba(BCI)NO3(H2O)2］n and ［Zn(BCI)2］n(HBCI= 1,3-bis(carboxymethyl)imidazolium),have been synthesized under solvothermal conditions and characterized by single crystal X-ray diffraction,elemental,powder X-ray diffraction and thermogravimetric analysis.Crystal structure analyses indicated that ［Ba(BCI)NO3(H2O)2］ncrystallizes in monoclinic system,space group Cc with a=1.316 2(11) nm,b=1.494 4(11) nm,c=0.851 7(7) nm,β=127.87°,Z=4.［Zn(BCI)2］n crystallizes in monoclinicsystem,space group Cc with a=1.721 6(5) nm,b=0.744 45(2) nm,c=1.290 6(4) nm,β=106.53°,Z=4.The coordination polymer［Ba(BCI)NO3(H2O)2］n was bridged by adjacent Ba2+ions through the BCI-l igand carboxyl oxygen atom to form a one-dimensional chain structure,which was further bridged by BCI-l igandtoform a two-dimensional mesh structure with {44} topology.The coordination polymer［Zn(BCI)2］n was bridged by Zn2+and the carboxyl oxygen atoms of the BCI-l igand to form a two-dimensional network structure with{44;62}topology.
