A mixed ligand complex of l‐phenyl‐3‐methyl‐4‐trifluoroacetyl pyrazolone‐5 (HPMTFP) and dimethyl sulfoxide (DMSO) with neodymium having molecular formula Nd(PMTFP) 3 · 2DMSO has been synthesized. Its crystal and molecular structures have been determined by a four‐circle X‐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)Å, β = 96.61 (3)°, Z = 4. The Nd atom is coordinated by eight oxygen atoms, which takes a distorted delta dodecahedron arrangement around the central Nd atom. The average bond length of Nd—O is 2.45 Å. The IR spectra have been discussed as well.
