Abstract: In this paper, the title coordination compound was synthesized, the crystal and molecular structure have been determined by single crystal X-ray diffraction analysis. The crystal is monoclinic with space group P2₁/n. The unit cell parameters arc: a=24.498(3)A, b=14.735(3)A, c=14.888(5)A, β=101.14(2)°, V=5285A3, Z=4. Each Ytterbium ion is surrounded by eight oxygen atoms, contributed by three PMBP and two water molecules, arranged at the vertexes of a square antiprism.

Keywords: coordination compound lanthanide 4-acetyl pyrazolone
