4-(Dimethylamino)phenyl ethynyl telluride

Abstract: The title compound, C10H11NTe, is the first organyl ethynyl telluride, R-Te-C[triple bond]C-H, to be structurally characterized. In the L-shaped molecule, the aryl moiety, viz. Me2NC6H4Te, is almost perpendicular to the Te-C[triple bond]C-H fragment. The Te-Csp2 bond [2.115 (3) Å] is significantly longer than the Te-Csp bond [2.041 (4) Å]. The Te-C[triple bond]C group is approximately linear [Te-C-C = 178.5 (4)° and C[triple bond]C = 1.161 (5) Å], while the coordination at the Te atom is angular [C-Te-C = 95.92 (14)°]. In the crystal structure, there are Csp-H...N hydrogen bonds which are perpendicular to the CNMe2 group; the N atom displays some degree of pyramidalization. Centrosymmetrically related pairs of molecules are linked by Te...[pi](aryl) interactions, with Te...Cg = 3.683 (4) Å and Csp-Te...Cg = 159.1 (2)° (Cg is the centroid of the benzene ring). These interactions lead to the formation of zigzag ribbons which run along c and are approximately parallel to (110).
