Three new rare earth metal-rich compounds, Gd6MTe2 (M = Co, Ni) and Er6RuTe2, were synthesized in direct reactions between the R, R3M, and R2Te3 (R = Gd, Er, M=Co, Ni, Ru). These materials all adopt the same Zr 6CoAl2 structure type with space group P6̄2m (No. 189, Z = 1). Single crystal structures of Gd6CoTe2 and Er6RuTe2 were determined and lattice parameters are a = b = 8.3799(5), c = 3.9801(4) Å, and a = b = 8.1473(5) Å, c = 3.9962(4) Å, respectively. Gd6NiTe2 was characterized by X-ray powder diffraction; lattice parameters are a = b = 8.412(2), c = 3.9577(9) Å. Metal-metal bonding correlations were analyzed using the empirical Pauling bond order concept. © 2003 Elsevier B.V. All rights reserved.
