Low-dimensional magnetic materials, which can simultaneously utilize the electrons’ spin and charge degrees of freedom for data storage, processing and transmission, exhibit significant potentials for applications in next-generation information technologies. However, the development of low-dimensional magnetic materials faces severe challenges such as the difficulties of experimental synthesis and characterization, usually low Curie temperatures, lack of effective modulation, and limited function integration. First-principles design of novel low-dimensional functional magnetic materials has thus emerged as a crucial approach to addressing these issues. In this context, organometallic systems have garnered widespread attentions due to their rich chemical tunability. Their diverse transition metal centers and extensive organic ligand libraries provide a vast design space for low-dimensional magnetic materials. The precisely controllable coordination environment can effectively modulate the charge and spin states of metal/ligand centers. Moreover, the coordination bonds between metals and ligands exhibit diverse and adjustable orbital coupling, offering an ideal platform for achieving high Curie temperatures and varied magnetic interactions. Additionally, the chemical modifiability and conformational flexibility of organic ligands facilitate the construction of magnetic phase-transition systems and multifunctional spintronic devices. This review aims to systematically summarize recent advances in the first-principles design of low-dimensional magnetic organometallic materials with targeted functions. Several key design strategies are highlighted, including methods for constructing stable magnets with long-range room-temperature ferrimagnetism, chemical modulation strategies for magnetic phase transitions, approaches to designing room-temperature multiferroic materials, principles for creating metal-organic materials with giant Rashba effects, design rules for bipolar magnetic molecules, inverse design of altermagnetic metal-organic frameworks (MOFs), and microscopic mechanisms of electric-field-controlled magnetism. Finally, the integration of machine learning methods to achieve low-dimensional metal-organic magnets with high magnetic anisotropy is discussed. By systematically outlining the unique advantages and existing challenges of organometallic systems in the design of low-dimensional magnetic materials, along with the latest experimental breakthroughs, this review is expected to provide theoretical guidance and technical pathways for future related researches.
