Intermetallic compound YbCuZnSb2 was synthesized and characterized by the single-crystal X-ray method. YbCuZnSb2 crystallizes in the CaAl2Si2-type structure (space group P-3m1) with lattice constants a = 4.43940(10) Å, c = 7.4139(3). Magnetic susceptibility measurements 2-300K show the nonmagnetic 4f14 ground state for ytterbium ions (Yb2+). YbCuZnSb2 demonstrates p-type conductivity; and the dependence of resistivity on temperature is of metallic character. The variation of Cu/Zn corelation in an ingot was observed without any imperfection of the type of.crystal structure This fact can testify to the existence of solid solution between YbZn2Sb2 and YbCuZnSb2 compounds.
