12-(2-Chlorophenyl)-7,11,13,16-tetraoxaspiro[5.2.5.2]cetane (2) was prepared by cyclohexanone and 5,5-bis(hydroxymethyl)-2-(2-chlorophenyl)-1,3-dioxane (1) which synthesized from the reaction of the o-chlorobenzaldehyde and pentaerythriol, or prepared by o-chlorobenzaldehyde and 9,9-bis(hydroxymethyl)-7,11-dioxaspiro[5,5]undecane (3) which synthesized from the reaction of the cyclohexanone and pentaerythriol. Compounds 1 and 2 were characterized by X-ray diffraction, elemental analysis, 1H NMR. Single crystal X-ray diffraction analyses reveal that compound 1 belongs to monoclinic system with space group P2(1)/n with a=0.56768(15) nm, b=0.9807(3) nm, c=2.1785(6) nm, a=90°, b=90.204(4)°, g=90°, V= 1.2128(5) nm3, Z=4, Dc=1.417 Mg/m3, μ=0.315 mm-1, F(000)=544. Compound 2 also belongs to monoclinic system with space group C2/c with a=1.5894(5) nm, b=1.5704(4) nm, c=2.8369(9) nm, a=90°, b=101.103(5)°, g=90°, V=6.948(4) nm3, Z=16, Dc=1.296 Mg/m3, μ=0.237 mm-1, F(000)=2880.
