|a We show that the previously unreported ternary ? phases Nb<sub>20.4</sub>Rh<sub>5.7</sub>Ge<sub>3.9</sub> and Nb<sub>20.4</sub>Rh<sub>5.7</sub>Si<sub>3.9</sub> are both superconductors with T<sub>c</sub> values of approximately 1.9 K. The superconducting transitions were characterized through temperature-dependent magnetic susceptibility, electrical resistance, and specific heat measurements. The Sommerfeld constants, ?, for Nb<sub>20.4</sub>Rh<sub>5.7</sub>Ge<sub>3.9</sub> and Nb<sub>20.4</sub>Rh<sub>5.7</sub>Si<sub>3.9</sub> are 89(1) mJ mol-f.u.<sup>?1</sup>K<sup>?2</sup> and 86(1) mJ mol-f.u.<sup>?1</sup>K<sup>?2</sup> (about 3.0 and 2.9 mJ mol-atom<sup>?1</sup> K<sup>?2</sup>), respectively. Here, the normalized specific heat jumps at T<sub>c</sub>, ?C/?T<sub>c</sub>, are approximately 1.39 for Nb<sub>20.4</sub>Rh<sub>5.7</sub>Ge<sub>3.9</sub> and 1.30 for Nb<sub>20.4</sub>Rh<sub>5.7</sub>Si<sub>3.9</sub>, consistent with both materials being weakly coupled BCS type superconductors.
