The structural phase exhibits a large noncentrosymmetric cubic unit cell with the a-parameter being within 1.208 \\leq a \\leq 1.215 nm. This phase is stable over a wider compositional range of LixRhBy (0.6 < x < 2, 1 < y < 2). The superconductivity, as well as the unit cell volume, is sensitive to the Li/B content but it is manifested with Tc \\geq 1.8 K over a wider compositional range: the highest Tc \\approx 3 K occurs for x : y \\approx 0.9:1.5 with a \\approx 1.209 nm.
