The crystal structure of Ce5Co4Ge13 was refined from single-crystal X-ray diffraction data. This new orthorhombic structure type (space group Cmmm, a = 4.265(1), b = 45.175(9), c = 4.293(1) Å) is a filled-up derivative of the Nb5Ga13 type and contains AlB2-, BaNiSn3and AuCu3-type slabs intergrown along [010]. The “interstitial” Co atoms are characterized by bicapped square-antiprismatic [Ce5Ge5] coordination.
