Abstract
A new modification of the title compound was obtained by the recrystallization from benzene solution. Th M e crystal structure has been determined by X-Ray diffraction: Crystal data; Ge6 (C6H5)12⋅ 5 (C6H6), Mw=1741.39 PI, a. =15.438(3) Å, c=19.111(2) Å, a74.90(1)°, β=70.29(2)°, γ =71.37(1)°, Z=2, R =0.054, Rw =0.046 for 9592 observed (_??_Fo_??_ ≥ 3σ (_??_Fo_??_) ) reflections.
There are two Ge6Ph12 molecules, both having a center of symmetry. The cyclohexagermane rings adopt chair conformations. As for the molecular packing, the dihedral angle between the 6-membered G e ring and that of the nearest neighbor is 58°. The packing is different from that of the Ge6Ph12 ⋅ 7benzene and the Ge6Ph12⋅ 2toluene.
