| Abstract: The title complex was synthesized by reaction of glycine and samarium perchloride in aqueous solution.The IR spectra of the complex was studied and the crystal structure was determined by X-ray diffraction method.The crystal belongs to triclinic with space group P1 and cell parameters:a=11.549(2),b=14.122(3),c=15.654(4)Å,α=97.01(2),β=102.70(2),γ= 105.43(2)°,V=2355.94(0.87)Å3and Z=2.The complex is an one-dimensional chain complex of infinite length.The two Sm atoms are coordinated by sixteen oxygen atoms,two of which coordinate to the two Sm atoms at the same time forming oxygen bridge bonds.The polyhydrons can be discribed as two tricappcd triprism.The N atoms of NH3+,groups and O atoms of CIO4- groups do not take part in the coordination to Sm atoms. |
