Crystals of NaPd3X2, (X= Si, Ge, Sn) were synthesized and their crystal structures investigated by single crystal X-ray diffraction. The previously reported structures of NaPd3Si2 and NaPd3Sn2 were confirmed. NaPd3Ge2 was found to have a different unit cell from that originally reported; therefore the structure was solved. It is an orthorhombically distorted version of the hexagonal CeCo3Be2-type structure, in space group Imma, with cell parameters a = 7.244(1) angstrom, b = 9.938(1) angstrom, c= 5.767(2)angstrom. The originally reported cell is explained through triple twinning of the true cell. The structure of NaPd3Ge2 fits the trend of decreasing X-X dimerization as a function of increasing period from Si Sn. All three compounds are metals showing weak diamagnetism with increasing resistivity from NaPd3Si2-NaPd3Sn2; no superconductivity is observed down to 2K. (C) 2015 Elsevier Ltd. All rights reserved.
