摘要
The title polymeric complex Ho(H 2saln) 1.5 (NO 3) 3 (H 2saln= N,N’ bissalicyclidene ethylenediamine) C 24 H 24 N 6O 12 Ho was prepared and its crystal was characterized by X ray diffraction. The ligand is dischiff base from salicylaldehyde and ethylenediamine. The complex crystallizes in trigonal system, space group P3c1 (No. 165), M r=753.42, a=15.818(2), c=16.978(3) , V=3681(2) 3, D x =1.360 g/cm 3, Z=4, μ =2.2286 mm -1 , F(000)=1492, R=0.049, R w =0.061. In the complex the coordination number of Ho(Ⅲ) is 9 with the geometry of a tricapped trigonal prism. All of the coordination atoms are oxygen atoms. The Ho(Ⅲ) ions are bridged by the dischiff base to form an infinite two dimensional polymeric network, parellel to the (001) plane.
