The crystal structures of GdCuAs2, GdCuAsu5Po.g5 and GdCuP2.20 have been investigated by the single crystal and powder methods. While GdCuAs2 (P4/nmm) retains the tetragonal HfCuSi2 structure (M. Brylak, M.H. Môller and W. Jeitschko, J. Solid State Chem. 115, 305 (1995)), GdCuAsusPo.85 (Pmmn, a = 3.849(1), b = 3.850(1), c = 9.871(3) À) and GdCuP220 (Pmm2, a = 5.3747(9), b = 5.3830(9), c = 9.7376(16) À) undergo orthorhombic distortions. The changes are significant in GdCuP2.20: P dimers are formed in the P layer along the a direction and there is an additional (but deficient) P site on one side of the layer that links the dimers. The GdCuAst.tsPo.ss structure was predicted by the Landau theory. According to this theory the transition from GdCuAs, to GdCuAst.tsPo.ss can be a continuous one, the transition from GdCuAst.15P0.8s to GdCuP22o is a first-order one. The transition to GdCuP^o occurs with twin formation. The electronic structure and bonding are analyzed by the extended Huckel tight-binding method. The conductivity and magnetic measurements for the arsenide and phosphide are reported.
