Abstract
Nine compounds from the series A 2M 3UQ 6 (A = K or Rb or Cs; M = Pd or Pt; Q = S or Se) were synthesized by reacting U, M, and Q in ACl or A 2Q x fluxes. These compounds crystallize with eight formula units in the NaBa 2Cu 3O 6 structure type, in space group Fmmm of the orthorhombic system. The structure contains hexagons formed from six edge-sharing square-planar coordinated M atoms, which in turn edge-share with trigonal-prismatically coordinated U atoms, forming layers along (010). These layers are separated by A atoms. Electrical resistivity measurements along the [100] direction of Rb 2Pd 3US 6 show typical semiconductor behavior. Magnetic susceptibility measurements on Rb 2Pd 3US 6 display marked magnetic anisotropy and unusually low magnetic moments owing to crystalline electric field effects.
