Two new noncentrosymmetric (NCS) solids were isolated via high-temperature, salt-inclusion reactions, Cs(2)Cu(7)(P(2)O(7))(4).6CsCl (1, CU-9) and Cs(2)Cu(5)(P(2)O(7))(3).3CsCl (2, CU-11). These copper(II) phosphates exhibit novel open-framework structures conceptually templated by extended Cs-Cl salt. The latter resides cooperatively in the channels upon the formation of the NCS Cu-P-O frameworks, leading to the formation of fascinating salt lattices centered by the NaCl-type core. These new discoveries are significant for they may give rise to a new route for the templated synthesis of NCS solids. We are to show here the structural correlation of the newly discovered hybrid solids, and the role of the chlorine atoms in the "intergrowth" of covalent/ionic sublattices.
通过高温盐包合反应分离出两种新的非中心对称（NCS）固体，即Cs₂Cu₇(P₂O₇)₄·6CsCl（1，CU - 9）和Cs₂Cu₅(P₂O₇)₃·3CsCl（2，CU - 11）。这些磷酸铜（II）呈现出由扩展的Cs - Cl盐在概念上模板化的新型开放框架结构。在NCS Cu - P - O框架形成时，后者协同存在于通道中，导致形成以NaCl型核为中心的迷人盐晶格。这些新发现意义重大，因为它们可能为NCS固体的模板合成开辟一条新途径。我们在此展示新发现的混合固体的结构相关性，以及氯原子在共价/离子亚晶格“共生”中的作用。
