Since many material properties are closely linked to its structure, understanding the structure formation is imperative when trying to engineer new materials. However, many competing effects impact the final structure formation, complicating accurate predictions. Here, we investigate 1,4-benzoquinone on Ag(111) and use CO-functionalized scanning probe microscopy in conjunction with density functional theory calculations to reveal the non-intuitive, tilted adsorption of the molecules. While the self-assembly of 1,4-benzoquinone on Ag(111) has been studied previously, our study provides additional clarification and insights into its structure that were inaccessible at that time.
