A new complex[Mn(DHTA)(bipy)0.5]n(1,H2DHTA=2,5-dihydroxy-1,4-benzenedicarboxylic acid,bipy=2,2΄-bipyridine)was hydrothermally synthesized and structurally characterized by elemental analysis,IR spectrum,single-crystal...A new complex[Mn(DHTA)(bipy)0.5]n(1,H2DHTA=2,5-dihydroxy-1,4-benzenedicarboxylic acid,bipy=2,2΄-bipyridine)was hydrothermally synthesized and structurally characterized by elemental analysis,IR spectrum,single-crystal and power X-ray diffraction.It belongs to monoclinic system,C2/c space group with a=12.874(13),b=11.302(12),c=17.352(18)Å,β=101.574(15)°,V=2474(4)Å3 and Z=4.It displays a one-dimensional zigzag chain-like structure,which was further extended into a three-dimensional supramolecular structure by hydrogen bonds andπ-πinteractions.Moreover,we analyzed Natural Bond Orbital(NBO)of 1 in using the PBE0/LANL2DZ method built in Gaussian 03 Program.The calculation results show the obvious covalent interaction between the coordinated atoms and Mn(Ⅱ)ion.展开更多
