Polycrystalline samples with nominal Y concentrations up to 40% were synthesized and characterized via electrical resistivity, magnetic susceptibility, and specific heat measurements. Y substitution reduces the lattice parameter \\textit{a} and unit cell volume \\textit{V}, and a correlation between the lattice parameter \\textit{c}, the La-O-La bond angle, and the superconducting critical temperature $T_c$ is observed.
