The crystal structures of the new compounds Ce2Rh12Si7 and Ce6Rh30Si19, extracted from an ingot of composition Ce9.5Rh56.9Si33.6, were investigated by X-ray single crystal diffraction methods. The title compounds crystallize in the hexagonal space group P63/m with unit cell parameters a=9.706(1) Å, c=3.8394(3) Å and a=15.698(2) Å, c=3.8571(4) Å, respectively. Ce2Rh12Si7 and Ce6Rh30Si19 represent members of a family of hexagonal structures with a short unit cell parameter c≈3.7 Å and with general formula Rn(n+1)T6(n2+1)M4n2+3, where R is the rare earth, T the transition metal, and M the element of the IV or V main group. Ce2Rh12Si7 crystallizes with the Ho2Rh12As7 type, ignoring the disordered arrangement of non-metal atoms on the c-axis. The structure of Ce6Rh30Si19 is closely related to that of Sc6Co30Si19.
