摘要：

The　synthesis　of　syn-photodimer　from　1,4-dihydropyridine　without　4-aryl　was　studied,　and　its　single　crystal　was　obtained　(C22H　30N2O8,　Mr　=　450.48).　It　crystallizes　in　monoclinic,　space　group　P21/c　with　a　=　11.937(2),　b　=　20.913(4),　c　=　9.763(2)　Å,　β　=　108.46(3)°,　V　=　2311.9(8)　Å3,　Z　=　4,　Dc　=　1.294　g/cm3,　F(000)　=　960,　μ　=　0.099　mm-1,　R　=　0.0640　and　wR　=　0.1464　for　4077　unique　reflections　with　1598　observed　ones　(I　>　2σ(I)).　It　is　shown　that　the　whole　molecular　structure　of　the　title　compound　is　a　twist-boat　conformation,　and　the　two　double　bonds　have　a　trend　of　potential　intramolecular　reaction　under　high-energy　irradiation.
