This work completes the study of the RNi6Si6 series (R = rare earth). While the RNi6Si6 compounds for R = La and Ce adopt the CeNi6Si6-type (tP52, P4/nbm, No. 125), surprisingly PrNi6Si6 crystallizes in the YNi6Si6 prototype (tP52, P − 4b2, No. 117) as do all the heavier lanthanides (but Lu). The YNi6Si6-type and its homolog CeNi6Si6 are two tetragonal ordered derivative of the cubic NaZn13-type structure. Lattice parameters for PrNi6Si6 are a = 7.7846(1) Å, c = 11.2144(1) Å, with a unit cell volume, Vobs = 679.585(5) Å3. The temperature dependence of the inverse magnetic susceptibility χ−1(T) follows the Curie–Weiss law, with calculated values of the effective magnetic moment (µeff) and Weiss temperature (Θpm) of 3.55 μB and − 4.5 K, respectively. While the observed µeff is very close to the theoretical value of 3.58 µB for the free Pr3+ ions, a negative value of the Weiss temperature suggests antiferromagnetic interactions in PrNi6Si6. Magnetization measurements confirm that PrNi₆Si₆ orders antiferromagnetically (AFM) below a Néel temperature (TN) of 9 K. The Ni atoms contribute negligibly to the magnetic properties of this phase. The specific heat of PrNi₆Si₆ is approximately 0.42 J K  − 1  g − 1. Measurements of electric and thermal transport reveal that PrNi₆Si₆ exhibits metallic behavior across a wide temperature range of 2–900 K, accompanied by a relatively low thermal conductivity of around 6 W K − 1 m − 1 at room temperature. Such properties, together with its high-temperature refractory behavior, make PrNi₆Si₆ worthy of consideration in technological applications where fairly good electrical conductivity should be accompanied by a limited thermal conductivity."}],"quality_controlled":"1","department":[{"_id":"MaIb"}],"article_processing_charge":"No","doi":"10.1007/s10853-024-10582-y","month":"02","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","_id":"19374","year":"2025","date_created":"2025-03-09T23:01:29Z","OA_type":"closed access","article_type":"original"}
