Abstract A novel tetrakis(4-(5,5-dimethyl-2-phenyl-1,3-dioxan-2- yl)phenyl)germane (2) was synthesized by the reaction of germanium(IV) tetrachloride with 4-(5,5-dimethyl-2-phenyl-1,3-dioxan-2-yl)phenyllithium. Colorless plate-shaped single crystals obtained from recrystallization in ether were characterized by the single-crystal X-ray diffraction. The organogermanium compound was crystallized in a noncentrosymmetric nonpolar tetragonal space group, I-4, and classified as a porous molecular material owing to the presence of two types of distinct channels as a result of intermolecular hydrogen bonding. Compound 2 exhibits a differential gas adsorption property. The powder second-harmonic generating (SHG) measurements indicate that compound 2 shows a SHG efficiency 10 times greater than those of α-SiO2 and type-1 nonphase-matchable.

四(4-(5,5-二甲基-2-苯基-1,3-二恶烷-2-基)苯基)锗烷单晶的制备与表征

摘要 通过四氯化锗（IV）与 4-（5 ,5-二甲基-2-苯基-1,3-二恶烷-2-基)苯基锂。在乙醚中重结晶得到的无色板状单晶通过单晶X射线衍射表征。有机锗化合物在非中心对称非极性四方空间群 I-4 中结晶，并且由于分子间氢键而存在两种不同的通道，因此被归类为多孔分子材料。化合物 2 表现出不同的气体吸附特性。粉末二次谐波产生 (SHG) 测量表明，化合物 2 的 SHG 效率比 α-SiO2 和 1 型非相位匹配高 10 倍。
