利用室温挥发方法合成了手性化合物[Cd（bbp）2（H2 O）2]·bbp ·2NO3·H2 O （bpp ＝1，3-二（4-吡啶基）丙烷）；利用X射线单晶衍射分析了产物的分子结构，并测定了其荧光光谱和固体圆二色光谱．结果表明，合成产物具有含一维手性链[Cd（bbp）2（H2 O ）2]n的手性超分子结构；其在室温下表现出中等强度的倍频效应，其二阶非线性极化率为尿素的0．4倍，是潜在的二阶非线性光学材料．此外，合成的手性化合物呈现弱的荧光，其固体圆二色光谱则呈现正的Cotton效应．

Chiral coordination complex [Cd(bbp)2 (H2 O)2 ]·bbp ·2NO3 ·H2 O (bpp = 1 ,3-bis (4-pyridyl)propane) was synthesized by room temperature evaporation method .The molecular structure of as-synthesized product was analyzed by single-crystal X-ray diffraction ,while its fluorescence spectrum and solid circular dichroism spectrum were also measured .It was found that as-synthesized coordination compound has chiral supermolecular structure containing one-dimensional chiral chain of [Cd(bbp)2 (H2 O)2 ]n .Besides ,the crystal of as-synthesized coordi-nation compound possesses modest second-harmonic generation (SHG) activity ,and its SHG activity is approximately 0 .4 times as much as that of urea ,showing potential application as a second-order nonlinear optical material .Moreover ,as-synthesized chiral compound shows weak fluorescence ,and its solid circular dichroism spectrum is dominated by positive Cotton effect .
