The structure of Pr3Co2Ge7.36 (Cmmm, a = 4.236 (1), b = 25.994(5), c = 4.272(1) Å, Z = 2) can be considered as a partly disordered derivative of the La3Co2Sn7 type. The Ge positions in the Pr4Ge8 cuboctahedra of the AuCu3-type slabs are conveniently described by two partly occupied sites, one of which is split. The Co and Ge atoms are characterized by square-antiprismatic, cubooctahedral, and trigonal-prismatic coordination.
