摘　　要：A new coordination compound [Ba（OBPT）2（H2O）2]·H2O was obtained at room temperature by the reaction of 4,6-bis（2-pyridyl）-1,3,5-triazin-2-ol（HOBPT） with BaCl2.It was characterized by elemental analysis,FTIR,TG analysis,powder X-ray diffraction analysis and single-crystal X-ray diffraction analysis.The complex crystallizes in the monoclinic P21/n space group,with a = 16.325（1）,b = 6.7977（5）,c = 24.164（2） ,β = 104.009（1）,V = 2601.8（3） 3,Z =4,C26H22BaN10O5,Mr = 691.88,Dc = 1.766 g/cm3,F（000） = 1376 and μ（MoKα） = 1.587 mm-1.The final R = 0.0282 and wR = 0.0724 for 5095 observed reflections with I 〉 2σ（I） and R = 0.0312 and wR = 0.0744 for all data.In the complex,the barium ion is ten-coordinated with six nitrogen atoms from two ligands,two deprotonated hydroxyl oxygen atoms from another two ligands and two coordinated water molecules to form a double stranded chain.The extensive supramolecular interac-tions lead to the formation of an infinite 2D framework.A new coordination compound [Ba（OBPT）2（H2O）2]·H2O was obtained at room temperature by the reaction of 4,6-bis（2-pyridyl）-1,3,5-triazin-2-ol（HOBPT） with BaCl2.It was characterized by elemental analysis,FTIR,TG analysis,powder X-ray diffraction analysis and single-crystal X-ray diffraction analysis.The complex crystallizes in the monoclinic P21/n space group,with a = 16.325（1）,b = 6.7977（5）,c = 24.164（2） ,β = 104.009（1）,V = 2601.8（3） 3,Z =4,C26H22BaN10O5,Mr = 691.88,Dc = 1.766 g/cm3,F（000） = 1376 and μ（MoKα） = 1.587 mm-1.The final R = 0.0282 and wR = 0.0724 for 5095 observed reflections with I 〉 2σ（I） and R = 0.0312 and wR = 0.0744 for all data.In the complex,the barium ion is ten-coordinated with six nitrogen atoms from two ligands,two deprotonated hydroxyl oxygen atoms from another two ligands and two coordinated water molecules to form a double stranded chain.The extensive supramolecular interac-tions lead to the formation of an infinite 2D framework.
