A new yttrium boride has been found to exist between YB{sub 12} and YB{sub 50}. A single phase was established at a nominal composition of [B]/[Y] = 25.5-26.0. X ray powder diffraction and electron diffraction analyses showed that the new YB{sub 25} phase has a monoclinic system with a = 0.82842(3) nm, b = 1.03203(3) nm, c = 0.58570(2) nm, {beta} = 90.402(3){degrees}, and space group I121(No. 5), I1m1 (No. 8), or I12/m1 (No. 12). Rare earth elements from Gd to Ho can also form compounds isostructural to YB{sub 25}.
