Conventional hydrogen bonding (H‐bonding) has been extensively studied in organic and biological systems. However, its role in transition metal chemistry, particularly with Group 11 metals (i.e. Cu, Ag, Au) as hydrogen bond acceptors, remains relatively unexplored. Through a combination of experimental techniques, such as Nuclear Magnetic Resonance (NMR), Infrared spectroscopy (IR), X‐Ray Diffraction (XRD), and computational calculations, several aspects of H‐bonding interactions with Group 11 metals are examined, shedding light on its impact on structural motifs and reactivity. These include bond strengths, geometries, and effects on electronic structures. Understanding the intricacies of hydrogen bonding within transition metal chemistry holds promise for various applications, including catalytic transformations, the construction of molecular assemblies, synthesis of complexes displaying anticancer activities, or luminescence applications (e.g. Thermally Activated Delayed Fluorescence, TADF). This review encompasses the most significant recent advances, challenges, and future prospects in this emerging field.

In the realm of chemical bonding, studying the weak interactions involving transition metal complexes is alluring. As an added bonus, it gives you a virtuous idea of the chemical reactivity of transition metal complexes and sheds light on the factors that affect their structure and behavior. The present perspective delineates the attractive Au•••H−N/C/O hydrogen bonds via extensive analysis by combining experimental and computational studies of their bonding situation. We delve into the characteristic properties of Au•••H interactions in gold complexes, incorporating the findings from recently synthesized stable organometallic gold(I)/(III) complexes. The literature was examined for illustrations of analogous molecular geometries to draw comparisons between these results. This perspective has covered the maximum examples of Au•••H−C, Au•••H−N, and Au••• H−O hydrogen bonding interactions from the recent literature, which are rarely visible in other reports. This perspective significantly improves our understanding of transition metal−hydrogen bonding (especially gold−hydrogen bonding) and its future applications.
