Keywords: metal nanoparticles; osmium; pair distribution function; surfactant-free synthesis; Findings Precious metals are limited resources, yet fundamental for a range of applications, such as in medicine or catalysis [1][2][3]. There are relatively few reports on osmium (Os) compared to

Surfactant-free syntheses, therefore, bear promising features not only for fundamental research but also for industrial scale production [22][23][24]. A surfactant-free synthesis method to produce Pt, Ir, Ru, or bimetallic NPs has recently been reported

• -free synthesis of precious metal nanoparticles (NPs) performed in alkaline low-boiling-point solvents has been recently reported. Monoalcohols are here investigated as solvents and reducing agents to obtain colloidal Os nanoparticles by using low-temperature (<100 °C) surfactant-free syntheses. The
