The structure of the metastable phase PdPb 0.2 As 0.8 ( m ) is isotypic with NiAs. The hexagonal unit‐cell parameters (293 K) are: P 6 3 / mmc , a = 3.803(1), c = 5.651(1) Å, U = 70.78 Å 3 ; Z = 2, D x = 9.75 g cm −3 ; Cu K α radiation. X‐ray powder diffraction data are reported. The JCPDS Diffraction File No. for PdPb 0.2 As 0.8 ( m ) is 33‐1490.
