The structures of (P(CH/sub 3/)/sub 4/)TaCl/sub 4/(dmpe)/sub 2/)/sub 3/Cl/sub 4/.4(CH/sub 3/)/sub 2/S (1) and TaCl/sub 4/(dmpe)/sub 2/ (2) have been determined by X-ray crystallography to examine the structural effects of adding one d electron to the d/sup 0/ cation TaCl/sub 4/(dmpe)/sub 2//sup +/. The TaCl/sub 4/(dmpe)/sub 2//sup +/ ion has a structure of the dodecahedral type previously found for similar Ta/sup v/ complexes; the bond lengths and angles are as follows: Ta-Cl, 2.430 (3) angstrom; Ta-P, 2.691 (5) angstrom; P-Ta-P, 72.1 (2)/sup 0/; Cl-Ta-Cl, 145.4 (2)/sup 0/. The neutral molecule, 2, has a structure that is approximately square antiprismatic with the following bond lengths: Ta-Cl, 2.505 (3) angstrom; Ta-P, 2.653 (2) angstrom. Compound 1 forms cubic crystals in the space group I43m with a unit cell edge of 16.726 (7) angstrom, a cell volume of 4679 (6) angstrom/sup 3/, and Z = 2. The Ta atoms reside on positions of 42m symmetry. Compound 2 forms orthorhombic crystals in the space group P2/sub 1/2/sub 1/2 with unit cell dimensions a = 10.765 (2) angstrom, b = 11.297 (4) angstrom, c = 9.595 (3) angstrom, V = 1167 (3) angstrom/sup 3/, and Z = 2. The molecules have a crystallographic twofold axis of symmetry.
