Abstract:A new magnesium metal-organic framework (MOF),Mg(H2O)2(oba2-)(1)(H2oba=4,4’-oxybis (benzoate)),was synthesized under hydrothermal conditions,and characterized by elemental analysis (EA) and infrared spectra(IR)studies. Single-crystal X-ray diffraction analysis shows that the compound belongs to the monoclinic system with space group P21/c and cell parameters are a=1.4085(3)nm,α=90°,b=1.0025 (2)nm,β=105.47(3)°,c=1.0198(2)nm,γ=90°,V=1.3878(5)nm^3,Z=4,R1=0.0405,wR2=0.0917.This com-pound is constructed from rod-like SBUs,the Mg-O-C rod-shaped SBUs connected by organic links to form a 2D net and further extended to be a 3D supramolecular structure via hydrogen bond interactions.
Keywords:magnesium coordination compound  rod-shaped SBUs  MOFs  hydrothermal synthesis
