摘要：
The title compound 4 methyl 4 hydroxy 2 pentone is obtained by the condensed reaction of acetone, and co crystallized with octamolybdate anion and tetra butyl ammonium cation. The crystal structure belongs to triclinic system, space group P1 , Mo 8C 44 H 98 O 30 N 2 M r=1902.77, a=11.512(6), b=12.790(3), c=13.395(4), α=65.22(2), β=78.26(4), γ=71.12(3), V=1689(1) 3, Z=1, D x =1\^869g/cm 3, F(000)=950, μ =14.79 cm -1 , final R =0.053 and R w =0.067. The orbital hybridization of C(53) and C(55) are sp 3 and sp 2 separately in (CH 3) 2COHCH 2COCH 3 and the catalysis of β octamolybdate anion might be present for the condensed reaction of acetone.
