摘要

A new one-dimensional Mg(Ⅱ) coordination polymer,[Mg(L)(phen)(H2O)] (1),has been hydrothermally synthesized by using 3,5-dinitro-salicylic acid (H2L) and 1,10-phenanthroline (phen).It crystallizes in monoclinic,space group C2/c with a =33.038(7),b =6.6481(13),c =22.750(5) A,β =126.99(3)°,V =3991.1(14) A3,Z =8,C19H12MgN4O8,Mr.=448.64,Dc =1.493 g/cm3,F(000) =1840,μ(MoKa) =0.146 mm-1,R =0.0559 and wR =0.0975.In 1,each L anion bridges two Mg(Ⅱ) atoms to give one-dimensional zigzag chains with the Mg…Mg separation of 5.34 A,which are extended by π-π stacking interactions between 1,10-phenanthroline ligands into a two-dimensional supramolecular layer.Moreover,the O-H…O hydrogen-bonding interactions further stabilize the layer structure of 1.The luminescent property was also studied for 1 in solid state at room temperature.In addition,natural bond orbital (NBO) analysis was performed by the B3LYP/LANL2DZ method in Gaussian 09 Program.The calculation results show obvious covalent interaction between the coordinated atoms and Mg(Ⅱ) ion.
