Tri-phenyl-tellurium chloride.

The asymmetric unit of the title compound, C18H15ClTe, contains two mol-ecules which are in inverted orientations. The compound displays a tetra-hedral geometry around the Te atom in spite of there being five electron domains. This is attributed to the fact that the lone pair is not sterically active. The dihedral angles between the three phenyl rings are 76.51 (16)/73.75 (16)/71.06 (17) and 78.60 (17)/77.67 (16)/79.11 (16)° in the two mol-ecules. The crystal packing features eight C-H⋯π inter-actions.

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes.
