  We report the growth and magneto-transport studies of Pd$_{3}$Bi$_{2}$S$_{2}$
(PBS) thin films synthesized by pulsed laser deposition (PLD) technique. The
magneto-transport study on pristine and post annealed films show the presence
of more than one type of charge carrier with a carrier concentration in the
range $0.6$ - $2.26~\times$ 10$^{21}$ cm$^{-3}$ and mobility in the range 0.96
- 1.73 $\times$ 10$^{2}$ cm$^{2}$/Vs. At low temperatures a logarithmic
increase in conductivity is observed which indicates the presence of weak
anti-localization (WAL). The magnetotransport data is analysed within the
Hikami-Larkin-Nagaoka (HLN) theory. It is found that temperature dependence of
the dephasing length can't be explained only by electron-electron scattering
and that electron-phonon scattering also contributes to the phase relaxation
mechanism in PBS films.
