| 摘 要： | A new three-dimensional supramolecule composed of copper-Schiff base complex,[Cu(naphdien)]Cl·H2O,where naphdien is Schiff base of 2-hydroxy-1-naphthaldehyde and diethyle-netriamine,has been synthesized and determined by single-crystal X-ray diffraction.It belongs to the monoclinic system,space group P21/c,with a=7.3490(15),b=7.0847(16),c=30.845(3)(A),β=95.33(3)°,V=1599.O(5)(A)3,Z=4,C15H20ClCuN3O2,Mr=373.33,Dc=1.551 g/cm3,μ=1.543mm-1,F(000)=772,R=0.0536 and wR=0.0927 for 2788 unique reflections with 1659 observed ones(I＞2σ(I)).In the crystal structure,mononuclear units[Cu(naphdien)]Cl·H2O are linked into a two-dimensional framework via strong hydrogen bonds,and extended into a three-dimensional supramolecular structure through π-π stacking interactions.
