IC 166 is an intermediate-age open cluster ($\sim 1$ Gyr) which lies in thetransition zone of the metallicity gradient in the outer disc. Its location,combined with our very limited knowledge of its salient features, make it aninteresting object of study. We present the first high-resolution spectroscopicand precise kinematical analysis of IC 166, which lies in the outer disc with$R_{GC} \sim 12.7$ kpc. High resolution \textit{H}-band spectra were analyzedusing observations from the SDSS-IV Apache Point Observatory Galactic EvolutionExperiment (APOGEE) survey. We made use of the Brussels Automatic StellarParameter (BACCHUS) code to provide chemical abundances based on a line-by-lineapproach for up to eight chemical elements (Mg, Si, Ca, Ti, Al, K, Mn and Fe).The $\alpha-$element (Mg, Si, Ca and whenever available Ti) abundances, andtheir trends with Fe abundances have been analysed for a total of 13high-likelihood cluster members. No significant abundance scatter was found inany of the chemical species studied. Combining the positional, heliocentricdistance, and kinematic information we derive, for the first time, the probableorbit of IC 166 within a Galactic model including a rotating boxy bar, andfound that it is likely that IC 166 formed in the Galactic disc, supporting itsnature as an unremarkable Galactic open cluster with an orbit bound to theGalactic plane.
