Abstract: The complex Sc(PMBP)3 has been synthsized, where HPMBP= 1-phenyl-3-methyl-4-benzoyl-pyrazolone-5. Its crystal structure has been determined with a four-circle X-ray diffractometer. The crystal is triclinic with space group P1. The cell parameters are as follows: a=3.090(2)nm, b=1.2034(6)nm, c=1.2025(6)nm, α=86.64(4), β=81.13(5), γ=81.11(5)°, V=4.362(4)nm3, Z=4. In the crystal Sc(III)ion is coordinated by six oxygen atoms from three PMBP molecules, so that the coordination number of Sc(III)is six, froming an octahedron.

Key words: 1-phenyl-3-methyl-4-benzoyl-pyrazolone-5, scandium complex, crystal structure
