  We report transport properties of single-crystalline Pd$_{3}$Bi$_{2}$S$_{2}$,
which has been predicted to host an unconventional electronic phase of matter
beyond three-dimensional Dirac and Weyl semimetals. Similar to several
topological systems, the resistivity shows field induced
metal-semiconductor-like crossover at low temperature. Large, anisotropic and
non-saturating magnetoresistance (MR) has been observed in transverse
experimental configuration. At 2 K and 9 T, the MR value reaches as high as
$\sim$1.1$\times$10$^{3}$ \%. Hall resistivity reveals the presence of two
types of charge carriers and has been analyzed using two-band model. In spite
of the large density ($>$ 10$^{21}$ cm$^{-3}$), the mobility of charge carriers
is found to be quite high ($\sim$ 0.75$\times$10$^{4}$ cm$^{2}$ V$^{-1}$
s$^{-1}$ for hole and $\sim$ 0.3$\times$10$^{4}$ cm$^{2}$ V$^{-1}$ s$^{-1}$ for
electron). The observed magneto-electrical properties indicate that
Pd$_{3}$Bi$_{2}$S$_{2}$ may be a new member of the topological semimetal
family, which can have a significant impact in technological applications.
