  We have successfully grown the single crystal of a low carrier density system
Y$_3$Ru$_4$Ge$_{13}$ which crystallizes in the cubic crystal structure with the
space group Pm3n. Y$_3$Ru$_4$Ge$_{13}$ exhibits super conductivity below 2.85 K
as determined from the electrical resistivity, magnetic susceptibility and heat
capacity measurements. The bulk measurements indicate multiband
superconductivity in this low carrier system. Hall effect measurements show
that the Hall coefficient R$_H$ is positive and it decreases rapidly with
temperature which is highly unusual. The simple estimation of the carrier
concentration gives a value (\sim 10$^{20}$/cm$^3$) which is 2-3 orders of
magnitude lower than that of a conventional metal like Cu which seems to
suggest that Y$_3$Ru$_4$Ge$_{13}$ is a semimetal that display multiband
superconductivity.
