摘要：

The compound [PPh4](3)[Cr(Te-4)(3)](DMF)-D-. has been synthesized from the reaction of Cr(CO)(6) with a polytelluride solution in dimethylformamide at 100 degreesC. The compound has been characterized by Te-125 NMR and single-crystal X-ray diffraction techniques. The compound crystallizes in the triclinic space group P (1) over bar, with a = 12,991(3) Angstrom, b = 14.782(3) Angstrom, c = 24.628(5) Angstrom, alpha = 90.63(3)degrees, beta = 104.45(3)degrees, gamma = 106.49(3)degrees, and Z = 2 (T = 153 K). The [Cr(Te-4)(3)](3-) anion consists of a Cr(III) center chelated by three Te-4(2-) ligands in a distorted octahedral environment. The anion has the Deltalambdalambdalambda (or Lambdadeltadeltadelta) conformation.
