New compounds Ce{sub 3}Rh{sub 4}Ge{sub 4} and Ce{sub 3}Rh{sub 3}IrGe{sub 4} as part of an extended solid-solution range of Ce{sub 3}Rh{sub 4{minus}x} Ir{sub x}Ge{sub 4} have been synthesized by the arc melting technique starting from the pure elements. The crystal structures of Ce{sub 3}Rh{sub 4}Ge{sub 4} and Ce{sub 3}Rh{sub 3}IrGe{sub 4} have been refined from single crystal counter data. Both compounds were found to be isotypic with the U{sub 3}Ni{sub 4}Si{sub 4}-type. The following lattice parameters were obtained: a = 0.40915(5), b = 0.42400(19), c = 2.50673(82) nm for Ce{sub 3}Rh{sub 4}Ge{sub 4} and a = 0.40839(7), b = 0.42437(6), c = 2.50403(39) nm for isotypic Ce{sub 3}Rh{sub 3}IrGe{sub 4}. Both compounds, Ce{sub 3}Rh{sub 4}Ge{sub 4} and Ce{sub 3}Rh{sub 3}IrGe{sub 4}, have been investigated at low temperatures by means of dc electrical resistivity and magnetic susceptibility measurements. No magnetic ordering has been detected above 2 K.
