A mixed ligand complex of 1-phenyl-3-methyl-4-trifluoroacetyl pyrazolone-5(HPMTFP)and dimethyl sulfoxide(DMSO)with neodymium having molecular formula Nd(PMTFP)_3·2DMSOhas been synthesized.Its crystal and molecular structures have been determined by a four-circleX-ray diffractometer.The complex crystallizes in monoclinic with space group P 2_1/n.a=21.897(4),b=23.339(4),c=8.958(2)(?),β=96.61(3)°,Z=4.The Nd atom is coordinated by eight oxygenatoms,which takes a distorted delta dodecahedron arrangement around the central Nd atom.Theaverage bond length of Nd-O is 2.45(?).The IR spectra have been discussed as well.
