Synthesis and X-ray Crystal Structure of a Methylene-bridged Glycoluril Dimer

摘要

The synthesis and X-ray crystal structure of a methylene-bridged glycoluril dimer 2 was reported.The methylene-bridged glycoluril dimer 2(C38H36Br4N8O12,Mr=1116.35) crystallizes in space group P1 with a=10.5802(6),b=16.8469(9),c=24.7673(14) ,α=98.00,β=96.263(1),γ=101.606(1)o,V=4239.3(4)3,Z=4,Dc=1.749 g/cm3,μ=3.869 mm-1 and F(000)=2224.It crystallizes in an S-shaped conformation that displays two ethoxycarbonyl groups on each face of the molecule.
