根据分子组分的化学性质合理设计晶体结构是有机固体化学中一个长期而令人兴奋的研究课题，也是无机固体化学中晶体工程的一个新兴课题。特别是，非中心对称结构，或那些缺乏反转对称，是重要的未来技术的基础上压电，热电，铁电和二次谐波产生（SHG）。表现出这些性质的材料为基础科学中与非中心对称（手性、极性或手性-极性）空间群相关的研究提供了一大类新的固体。由顶点连接的八面体组成的结构在无机固体中是常见的。我们的亮点的主题是线性，锯齿形或螺旋链的理性合成时，两个顶点的八面体，这是相邻的（顺式）或相反（反式），连接。
The rational design of crystal structures based on the chemical nature of molecular components, a longstanding and exciting research topic in organic solid state chemistry, is an emerging theme of crystal engineering in inorganic solid state chemistry. In particular, noncentrosymmetric structures, or those lacking inversion symmetry, are important for future technologies that are based on piezoelectricity, pyroelectricity, ferroelectricity and second harmonic generation (SHG). Materials that exhibit these properties provide a large and new class of solids for studies in basic science associated with the noncentrosymmetric (chiral, polar, or chiral–polar) space groups. Structures comprised of vertex-linked octahedra are common in inorganic solids. The subject of our Highlight is the rational synthesis of linear, zigzag or helical chains when two vertices of an octahedron, which are either adjacent (cis) or opposite (trans), are linked.
