Cadmium Compounds

New intermetallic compounds RE4TCd (RE = Y, La-Nd, Sm, Gd-Tm, Lu; T = Ni, Pd, Ir, Pt) were synthesized by melting of the elements in sealed tantalum tubes in a highfrequency furnace. They crystallize with the Gd4RhIn-type structure, space group F 4̄3m, Z = 16. The four gadolinium compounds were characterized by single crystal X-ray diffractometer data: a = 1361.7(1) pm, wR2 = 0.062, 456 F2 values, 19 variables for Gd4NiCd; a = 1382.1(2) pm, wR2 = 0.077, 451 F2 values, 19 variables for Gd4PdCd; a = 1363.6(2) pm, wR2 = 0.045, 494 F2 values, 19 variables for Gd4IrCd; a = 1379.0(1) pm, wR2 = 0.045, 448 F2 values, 19 variables for Gd4PtCd. The rare earth atoms build up transition metal-centered trigonal prisms which are condensed via common corners and edges, leading to three-dimensional adamantane-related networks. The cadmium atoms form Cd4 tetrahedra which fill voids left in the prisms’ network.

New Compounds

Structural characteristics of a number of ternary rare earth/transition metal/aluminium compounds are hexagonal nets of the AlB 2-type, Kagomé nets and tetragonal pyramides. Crystal structures of the new compounds in the ternary Yb-T-Al systems contain units and sections of them. Kagomé nets stacked in an ..ABAB.. sequence are observed in YbAg1.5Al0.5 ( MgZn 2-type). The crystal structure of Yb8Ag21Al45 is related to the BaHg 11-type. YbAu0.8Al3.2 ( CaZn 2 Al 2-type) contains tetragonal pyramides which are connected by common edges. Fragments of the AlB 2- and BaAl 4-type structure are present in Yb5Au15Al16. YbPdAl2 and YbPtAl2 ( YbPdAl 2-type) contain pentagonal prisms as the characteristic structural elements.
