Crystal Structure of 1,4-Bis(triiodogallium(III))-1,4-bis(2,4,6-tri-tert-butylphenyl)-1,4-diphosphabuta-1,3-diene

Abstract

The crystal-structure properties of [(I₃Ga)₂{P(C₆H₂Bu^t₃-2,4,6)CH}₂]·(C₇H₈) are: monoclinic, space group C2/c with a = 17.506(4)Å, b = 14.799(3)Å, c = 22.861(5)Å, β = 104.85(3)°, V = 5725(2)ų, Z = 4, R₁ = 0.0735, wR₂ = 0.1781 for 3869 reflections (I > 2σ(I)). The title compound represents the first structurally characterized complex of a 1,4-diphosphabutadiene with a main-group metal fragment.
