摘　　要：The title compound 9-（2-hydroxy-5-nitrophenyl）-9H-dibenzo[c,h]-2,7,10-trioxan-thene-1,8-dione DMF solvate （C28H20N2O9,Mr=528.46） was synthesized and crystallized.The crystal belongs to the triclinic system,space group P1 with a=10.210（3）,b=10.698（4）,c=12.522（4）,α=92.214（6）,β=113.751（5）,γ=105.040（5）°,Z=2,V=1193.0（7）3,Dc=1.471 g·cm-3,μ（MoKα）=0.112 mm-1,F（000）=548,R=0.0444 and wR=0.1141 for 2667 observed reflections （I 〉 2σ（I））.X-ray analysis reveals that atoms C（1）,C（2）,C（3）,C（4）,C（5） and O（1） on the new 4H-pyran ring are slightly distorted,forming a half-chair conformation.The title compound 9-（2-hydroxy-5-nitrophenyl）-9H-dibenzo[c,h]-2,7,10-trioxan-thene-1,8-dione DMF solvate （C28H20N2O9,Mr=528.46） was synthesized and crystallized.The crystal belongs to the triclinic system,space group P1 with a=10.210（3）,b=10.698（4）,c=12.522（4）,α=92.214（6）,β=113.751（5）,γ=105.040（5）°,Z=2,V=1193.0（7）3,Dc=1.471 g·cm-3,μ（MoKα）=0.112 mm-1,F（000）=548,R=0.0444 and wR=0.1141 for 2667 observed reflections （I 〉 2σ（I））.X-ray analysis reveals that atoms C（1）,C（2）,C（3）,C（4）,C（5） and O（1） on the new 4H-pyran ring are slightly distorted,forming a half-chair conformation.
