Metal clusters exist at the intersection of molecules and nanoparticles, embodying both molecular and nano-scale characteristics. This interdisciplinary field is rapidly expanding, with significant implications for chemistry, catalysis, materials science, and nanotechnology. The third volume in this series presents recent advancements in metal clusters through approximately 20 contributions that offer a comprehensive overview. Topics explored include inter-electron repulsion in transition series chemistry, stereochemical activity in heavier main group element compounds, and the nuances of close packing. Contributions also delve into praseodymium diiodide, centered zirconium clusters, titanium niobium oxychlorides, and trinuclear molybdenum and tungsten cluster chalcogenides. Other discussions cover the current state of (B, C, N)-compounds of calcium and lanthanum, polar intermetallics, rare earth Zintl phases, and structure-property relationships in intermetallics. The volume further addresses ternary and quaternary niobium arsenide Zintl phases, cation-deficient quaternary thiospinels, and innovative hybrid materials from salt inclusion synthesis. Additionally, it examines hydrogen bonding in metal halides, the synthesis and catalytic properties of titanium nitride nanoparticles, and new scintillation materials in borophosphate systems. With a focus on education, this volume is valuable for both students and specialists alike
