 Abstract: The crystal structure of Sc3Ir4Si13+x (x = 0.22) [space group Pm (3) over barn, a = 8.4651(1) angstrom] is found to be a new disordered variant of the primitive cubic Yb3Rh4Sn13 Remeika prototype. The suicide is stable in the narrow temperature range of 1283-1397 degrees C and reveals metallic properties. The crystal structure of Sc4Ir7Ge6 [U4Re7Si6 type, space group Im (3) over barm, a = 8.1397(8) angstrom] is refined for the first time. The electronic band structure calculations reveal that the properties of this germanide can be explained based on the free electron gas model. Both compounds reveal close structural relationships to the simple perovskite structure.
