Abstract
In benzyltriphenyllead, [Pb(C6H5)(3)(C7H7)], (I), and dibenzyldiphenyl lead, [Pb(C6H5)(2)(C7H7)(2)], (II), each Pb atom is in the centre of a distorted tetrahedron. In (I) the C(Bz)-Pb-C(Ph) angles [110.4(3)-113 .1(3)degrees] are larger than the C(Ph)-Pt-C(Ph) angles [106.6 (3)-107 .5 (3)degrees)] suggesting a steric effect of the benzyl group (Bz). T he angles in (II) [C(Bz)-Pb-C(Bz) 107.8 (3)degrees; C(Bz)-Pb-C(Ph) 104 .6 (3) and 113.1 (3)degrees; C(Ph-Pb-C(Ph) 111.1 (3)degrees] reflect a more distinct distortion, but no similar steric effect of the benzyl groups is clearly recognizable.
