Crystal structure of 2,2,3,3-tetra­methyl-1,1,1,4,4,4-hexa­phenyl­tetra­germane

The mol­ecule of the title compound, C(40)H(42)Ge(4), lies with its central Ge—Ge bond on an inversion centre giving rise to a zigzag backbone of four tetra­hedrally coordinated Ge atoms. The symmetrically independent Ge—Ge bonds are slightly shorter than in other organo­tetra­germanes whereas the G...

Descripción
Sumario:The mol­ecule of the title compound, C(40)H(42)Ge(4), lies with its central Ge—Ge bond on an inversion centre giving rise to a zigzag backbone of four tetra­hedrally coordinated Ge atoms. The symmetrically independent Ge—Ge bonds are slightly shorter than in other organo­tetra­germanes whereas the Ge—C(Ph) (Ph = phen­yl) and Ge—C(Me) (Me = meth­yl) distances have their usual values. In the crystal, (010) layers of Ph(6)Me(4)Ge(4) mol­ecules with a parallel orientation of the Ge(4) backbone exist, held together by van der Waals forces only. Main bond lengths in organo-substituted oligogermanes are compared.
