The modification of inorganic two‐dimensional (2D) materials with organic functional motifs is in high demand for the optimization of their properties, but it is still a daunting challenge. Organic metal chalcogenides (OMCs) are a type of newly emerging 2D materials, with metal chalcogenide layers covalently anchored by long‐range ordered organic functional motifs, these materials are extremely desirable but impossible to realize by traditional methods. Both the inorganic layer and organic functional motifs of OMCs are highly designable and thus provide this type of 2D materials with enormous variety in terms of their structure and properties. This Minireview aims to review the latest developments in OMCs and their bulk precursors. Firstly, the structure types of the bulk precursors for OMCs are introduced. Second, the synthesis and applications of OMC 2D materials in photoelectricity, catalysis, sensors, and energy transfer are explored. Finally, the challenges and perspectives for future research on OMCs are discussed. With metal chalcogenide layers covalently anchored by long‐range ordered organic functional motifs, organic metal chalcogenides are a type of newly emerging 2D materials, which are exquisitely desired but impossible to realize by traditional methods for the synthesis of 2D materials. This Minireview gives a perspective on the structural design of bulk precursors, exfoliation methods, applications, and discusses research directions based on recently published work.
