摘要：

The title compounds 4,4’-oxobis(propham) ((?)n) (C20H24N2O5, Mr.=372.41) was synthesized by the addition reaction of corresponding 4,4’-oxobisphenyl diisocyanate with isopropanol. The crystal structure was determined by X-ray diffraction method. The crystal is triclinic system, space group P-1 with a=8.5107(17), b=9. 1164(18), c=14.5701(3)A, α=80.44(3),β=85.25(3), γ =62.88(3)°, V=992.2(3)A3, Z=2 , Dc=1.247g/cm3, F (000)=396, R =0.0520 , wR2=0.1434 for 4336 observed reflections with [I>2 σ(I)]. X-ray analysis reveals that interatomic distances for O(2)-C(7) is 1.2142(19), O(4)-C(17) is 1.2136(18)A, obviously show they form C=O double bonds.
