The field of coordination polymers and metal–organic frameworks has to date focused on the crystalline state. More than 60,000 crystalline metal–organic framework structures, formed from highly ordered arrays of metal nodes connected by organic ligands in at least one dimension, have been identified. However, interest in non-crystalline systems is growing, with amorphous solids, glasses and liquids identified as possessing similar metal–ligand bonding motifs to their crystalline cousins. In this Review, we provide an overview of the structural design, properties and potential applications of non-crystalline coordination polymers and metal–organic frameworks. In particular, we highlight recent reports of glasses that result from the melt quenching of the liquid states of these topical classes of materials. Finally, we provide a perspective on the future of the non-crystalline domain of coordination polymers and metal–organic frameworks.

迄今为止，配位聚合物和金属有机骨架的领域都集中在晶态上。已经鉴定出超过60,000种由有机节点至少一维连接的高度有序的金属节点阵列形成的晶体金属-有机框架结构。但是，人们对非晶体系统的兴趣与日俱增，无定形的固体，玻璃和液体被确定为具有与其晶体表亲相似的金属-配体键合图案。在本综述中，我们概述了非晶态配位聚合物和金属有机骨架的结构设计，性能和潜在应用。特别是，我们重点介绍了玻璃的最新报道，这些报道是由这些局部材料类别的液态的熔融淬火引起的。最后，
