摘要：

[P(C6H5)4]2[Pd(Te4)2].C3H7NO (I), M(r) = 1806, orthorhombic, Pbca, a = 29.611 (10), b = 16.291 (6), c = 23.325 (9) angstrom, V = 11251.8 angstrom3, Z = 8, D(x) = 2.17, D(m) = 2.20 (1) g cm-3 (by flotation in CHBr3/heptane), Mo K-alpha, lambda = 0.71069 angstrom, mu = 44.9 cm-1, F(000) = 6680, T = 296 K, final R = 0.044, wR = 0.049 for 4453 reflections with F(0)2 > 3-sigma(F(0)2). The structure is composed of Ph4P+ cations, [Pd(Te4)2]2- anions and DMF molecules. The [Pd(Te4)2]2- complex features a nearly square-planar Pd2+ atom chelated by two Te(4)2- ligands. The PdTe4 five-membered rings are puckered forming an envelope conformation. The mean Pd-Te bond distance is 2.587 (2) angstrom. The mean Te-Te bond distance is 2.74 (3) angstrom.
