The plumbides Ca T Pb 2 ( T = Rh, Pd), Eu T Pb 2 ( T = Rh, Pd, Pt), Sr T Pb 2 ( T = Rh, Pd, Pt) and Ba T Pb 2 ( T = Pd, Pt) were obtained by direct reactions of the elements in sealed tantalum tubes in an induction furnace. The moisture sensitive polycrystalline samples were characterized by X-ray powder diffraction. They crystallize with the orthorhombic MgCuAl 2 -type structure, space group Cmcm . The structures of CaRhPb 2 ( a = 433.78(3), b = 1102.06(8), c = 798.43(6) pm, wR = 0.0285, 432 F 2 values and 16 variables) and EuPdPb 2 ( a = 457.24(5), b = 1158.27(13), c = 775.73(8), wR = 0.0464, 464 F 2 values and 16 variables) were refined from single crystal X-ray diffractometer data. The characteristic structural motif is the distorted tetrahedral substructure built up by the lead atoms with Pb–Pb distances of 326–327 pm in CaRhPb 2 and of 315–345 pm in EuPdPb 2 . With increasing size of the alkaline earth (Eu) cation, the lead substructure becomes more anisotropic with a shift of the [ T Pb 2 ] polyanions from three- to two-dimensional, leading to significantly increased moisture sensitivity. Temperature dependent magnetic susceptibility studies reveal Pauli paramagnetism for SrRhPb 2 , SrPtPb 2 , BaPdPb 2 and BaPtPb 2 . EuRhPb 2 and EuPdPb 2 are Curie–Weiss paramagnets with stable divalent europium as is also evident from 151 Eu Mössbauer spectra. EuRhPb 2 is a ferromagnet with T C = 17.7(2) K, while EuPdPb 2 orders antiferromagnetically at T N = 15.9 K. This is in agreement with the full magnetic hyperfine field splitting of the 151 Eu Mössbauer spectra at T = 6 K.
