使用非手性有机胺以2-甲基苯并咪唑和1，4-二氮杂双环[2.2.2]辛烷为结构导向剂和配体，水（溶剂）热法合成了两种手性亚磷酸锌配合物[Zn（C（8）H（8）N（2））（HPO（3））] 1和（C（6）H（13）N（2））[Zn（3）（C（6）H（12）N（2））（HPO（3））（3）（H（2）PO（3））] 2，在手性空间群P2（1）2（1）2（1）中结晶。单晶结构分析表明，化合物1由ZnO（3）N和HPO（3）单元交替组成，呈现中性的一维手性链。有趣的是，有机配体与无机链通过氢键以氢键螺旋方式相互作用。化合物2是由{Zn（3）P（4）}畸变的二级结构单元（SBU）构成的具有16-MR通道的三维手性开放骨架。有机胺分子起着配体和抗衡阳离子的双重作用。
Employing achiral organic amines (2-methylbenzimidazole and 1,4-diazabicyclo[2.2.2]octane) as the structure-directing agent and ligand, two chiral zincophosphites, [Zn(C(8)H(8)N(2))(HPO(3))] 1 and (C(6)H(13)N(2))[Zn(3)(C(6)H(12)N(2))(HPO(3))(3)(H(2)PO(3))] 2, have been hydro(solvo)-thermally synthesized, crystallizing in the chiral space group P2(1)2(1)2(1). Single-crystal structural analysis reveals that compound 1 consists of alternating ZnO(3)N and HPO(3) units exhibiting a neutral one-dimensional chiral chain. Interestingly, the organic ligands interact with the inorganic chain via hydrogen-bonds in hydrogen-bonded helix fashion. Compound 2, a three-dimensional chiral open framework with 16-MR channels, is formed by the distorted {Zn(3)P(4)} secondary building unit (SBU). The organic amine molecules play dual roles as both ligands and countercations.
