| Abstract: | The title compound 4-methyl-4-hydroxy-2-pentone is obtained by the condensed reaction of acetone, and co-crystallized with octamolybdate anion and tetrabutyl-ammonium cation. The crystal structure belongs to triclinic system, space group P1, Mo8C44H98O30N2 Mr= 1902.77, a=11. 512(6), b=12. 790(3), c=13. 395(4)A, α=65. 22(2), β=78. 26(4), γ=71. 12(3), V=1689(1) A3, Z=1, Dx=1. 869g/cm3, F(000)=950, μ=14.79 cm-1, final R=0. 053 and Rw=0. 067. Theorbital hybridization of C (53) and C (55) are sp3 and sp2 separately in (CH3)2COHCH2COCH3 and the catalysis of β-octamolybdate anion might be present for the condensed reaction of acetone. |
