摘要
Hydrothermal reactions of Nd(ClO4)(3)center dot 6H(2)O, Gd(ClO4)(3)center dot 6H(2)O and Er2O3 with H(3)NTA (nitrilotriacetic acid) afford three new lanthanide coordination polymers, {[Nd(NTA)(H2O)]center dot 2H(2)O}(n) (1), {[Gd(NTA)(H2O)]center dot 2H(2)O}(n) (2) and {[Er(NTA)(H2O)]center dot H2O} n (3), characterized by elemental analysis and IR spectroscopy. X-ray single crystal structural analyses showed that 1 and 2 are an isomorphous 2D-layered framework containing the nine-coordinated Nd(III) (or Gd(III)), and woven into a 3D suprastructure by interlayer hydrogen bonding while 3 is a 3D structure with eight-coordinate Er(III).
