Abstract
A mixed ligand neodymium complex containing 1-phenyl-3-methyl-4-trifluoroacetyl-pyrazol-5-one (HPMTFP) and 1-phenyl-3-methyl-pyrazol-5-one (PMP), with molecular formula Nd (PMTFP)3·PMP·H2O was synthesized. Its crystal and molecular structure has been determined by single crystal X-ray diffraction method. The complex crystallizes in monoclinic system with space group C52-P21/n. There are four formula units in a cell of dimensions a = 12.837(3), b = 23.763(5), c = 16.810(4) A, β = 109.58(2)°. The structure has been refined by full-matrix least-squares techniques to a final R value of 0.0487 and Rw value of 0.432. The neodymium atom is coordinated to eight oxygen atoms with the average Nd—O bond length 2.439A. Its thermostability, and mass spectrum have been discussed.
