Abstract

The Ph4E and Ph3E-E'R3 compounds have a packing coefficient of 0.73 and induce their individual molecular symmetry in the crystal lattice. The molecular symmetry of the compounds are not affected by the close packing of Ph4E homologues or by the introduction of a methyl group in the ortho position. The Ph3Sn-GeMe3 and Ph3Ge-SnMe3 complexes exhibit isostructural orthorhombic packing due to the presence of asymmetric Sn-Ge dumbbell. On the other hand, the hexaphenyl derivatives form unit cells with triclinic and monoclinic symmetries.
