Two new intermetallic compounds RCo(3)Si(4) (R = Pr, Nd) with tetragonal NaZn13-derivative structure have been synthesized. Their crystal structures have been determined by X-ray powder diffraction and refined by the Rietveld technique. The space group for the tetragonal structure is 14/mcm. The lattice parameters are a = 7.789(1) Angstrom, c = 11.509(2) Angstrom and a = 7.791(2) Angstrom, c = 11.516(3) Angstrom for PrCo3Si4, and NdCo3,Si, respectively. The Si atoms strongly prefer to occupy the crystallographic 161(2) position.
