Single crystals of a new intermetallic gallide, R-CePd{sub 3}Ga{sub 8}, have been synthesized from excess molten gallium. Single-crystal X-ray diffraction reveals that R-CePd{sub 3}Ga{sub 8} crystallizes in the R-3m space group with a=b=c=8.4903(10) {angstrom} and {alpha}={beta}={gamma}=89.993(17). R-CePd{sub 3}Ga{sub 8} is a variant of the cubic BaHg{sub 11} structure type with three structural units: a Ce-centered polyhedron, a distorted cube of Pd{sub 2}Ga{sub 6} and a Pd-centered cuboctahedron. The distortions of these units are compared to a undistorted analogous units in intermetallic compounds with BaHg{sub 11} structure type. Field and temperature-dependent magnetization measurements on R-CePd{sub 3}Ga{sub 8} reveal a paramagnetic material with strong antiferromagnetic correlations and a magnetization consistent with Ce{sup 3+}. Electrical resistance measurements indicate Kondo behavior between localized Ce{sup 3+} magnetic moments.
