Abstract: The reaction of 1,4-dilithiotetraphenylbutadiene with germanium(1V) chloride and tin(1V) chloride affords heterocycles Ph4C4GeCl2, I and Ph4C4SnCl2, II. Compounds I and II, which feature a planar tetraphenylbutadiene backbone, were characterized by elemental analyses, 1H and 13C NMR spectroscopy and single crystal X-ray diffraction. The coordination environments for germanium and tin are distorted tetrahedra with bond angles spanning 35.35° for I and 24.86° for II. The Ge—Cl and bond distances are 2.134 Å and 2.143 Å in I, while the Sn—C1 and bond distances are 2.313 Å and 2.312 Å in II.

Keywords: Germanium(IV) chloride, tin(IV) chloride
