“…Although there is no room for interpolations, structures encoding chemical information about similarity and order can be used, as shown by Klein and coworkers [60,61,62]. 23 They have estimated properties of unknown substances, which makes foreseeable using the ordered hypergraph structure to estimate unknown properties of known elements.…”

For more than 150 years the structure of the periodic system of the chemical elements has intensively motivated research in different areas of chemistry and physics. However, there is still no unified picture of what a periodic system is. Herein, based on the relations of order and similarity, we report a formal mathematical structure for the periodic system, which corresponds to an ordered hypergraph. It is shown that the current periodic system of chemical elements is an instance of the general structure. The definition is used to devise a tailored periodic system of polarizability of single covalent bonds, where order relationships are quantified within subsets of similar bonds and among these classes. The generalised periodic system allows envisioning periodic systems in other disciplines of science and humanities.

We celebrate 150 years of periodic systems that reached their maturity in the 1860s. They began as pedagogical efforts to project corpuseso fs ubstances on the similarity and order relationshipso ft he chemical elements. However,t hese elements are not the canned substances wrongly displayed in many periodic tables, but rather the abstract preserved entitiesi nc ompound transformations. We celebrate the systems, rather than their tables or ultimate table. The periodic law,w ea rgue, is not an all-encompassing achievement, as it does not apply to every property of all elements and compounds.P eriodic systemsh ave been generaliseda so rdered hypergraphs, which solves the longlasting question on the mathematical structureo ft he systems.

2,4,9‐Triazaadamantanes with “Clickable” Groups: Synthesis, Structure and Applications as Tripodal Platforms

2,4,9-Triazaadamantanes (TRIADs) are promising yet scarcely available, conformationally rigid platforms for potential applications in the design of functional molecules and materials. Here, we report a facile synthesis of various N-and C7substituted 2,4,9-triazaadamantanes, starting from amines and 4-allylhepta-1,6-dienes. A focus was placed on the synthesis of 2,4,9-triazaadamantanes bearing reactive groups (NH 2 , propargyl, OH) on the bridge nitrogen atoms, which were then used to decorate the 3D scaffold by hydrazone, triazole, and boron-[a] Dr. A
