We report the discovery of a superconductor YGe3, Static magnetic susceptibility measurements show that the transition temperature T-c = 1.9-2.1 K (10-90% values). The zero resistivity temperature is attained below 2.2 K. Powder X-ray diffraction patterns indicate that this compound has the orthorhombic DyGe3-type structure with space group Cmcm. A refinement of the lattice parameters of the unit cell, determined by the method of least squares using the fifteen intense reflections for 2 theta < 60 degrees, reveals that the lattice parameters a = 4.0497(1) angstrom, b = 20.801(1) angstrom and e = 3.9174(1) angstrom for the compound YGe3.
