  We report synthesis, structural details and complete superconducting
characterization of very recently discovered Nb2PdS5 new superconductor. The
synthesized compound is crystallized in mono-clinic structure. Bulk
superconductivity is seen in both magnetic susceptibility and electrical
resistivity measurements with superconducting transition temperature (Tc) at
6K. The upper critical field (Hc2), being estimated from high field
magneto-transport measure-ments is above 240kOe. The estimated Hc2(0) is
clearly above the Pauli paramagnetic limit. Heat capacity measurements show
clear transition with well defined peak at Tc, but with lower jump than as
expected for a BCS type superconductor. The Sommerfield constant and Debye
temperature as determined from low temperature fitting of heat capacity data
are 32mJ/moleK2 and 263K respectively. Hall coefficients and resistivity in
conjugation with electronic heat capacity indicates multiple gap
superconductivity signatures in Nb2PdS5. We also studied the impact of
hydrostatic pressure on superconductivity of Nb2PdS5 and found nearly no change
in Tc for the given pressure range.
