Crystal engineering, the field of chemistry that studies the design, properties, and applications of crystals, is exemplified by the emergence of coordination networks (CNs). CNs are comprised of metal cations or metal clusters linked into 2D or 3D networks by organic and/or inorganic ligands. Early studies on CNs tended to focus upon design using self-assembly and/or reticular chemistry, but interest in CNs has grown exponentially as a consequence of their potential utility in catalysis, purification, sensing, and gas storage. Whereas the use of organic ‘linker ligands’ has afforded >75 000 metal-organic frameworks (MOFs), hybrid CNs (HCNs) sustained by both inorganic and organic linkers remain understudied. We herein review design approaches to HCNs and recent developments concerning their exceptional gas-separation performance.

晶体工程是研究晶体的设计，性质和应用的化学领域，它以配位网络（CN）的出现为例。CN由通过有机和/或无机配体连接成2D或3D网络的金属阳离子或金属簇组成。对氯化萘的早期研究倾向于集中于使用自组装和/或网状化学的设计，但是由于氯化萘在催化，纯化，感测和气体存储方面的潜在用途，因此对氯化萘的兴趣呈指数增长。尽管使用有机“接头配体”已提供了> 75 000个金属-有机骨架（MOF），但仍未充分研究由无机和有机接头维持的杂化CN（HCN）。在此，我们将回顾HCN的设计方法以及有关其出色的气体分离性能的最新发展。
