Bulky Arylgallium and Indium Derivatives with Co(CO)₄ and Mn(CO)₅ Substituents

Abstract

Abstract Further investigation of the reaction of Ar*GaCl 2 (Ar* = 2,4,6‐ t ‐Bu 3 C 6 H 2 ) with Na[Mn(CO) 5 ] resulted in the new compound, [Ga(Ar*){Mn(CO) 5 } 2 ] 2 . The new indium compounds, [In(Ar*){Co(CO) 4 } 2 ] 3 and [In(Ar*){Mn(CO) 5 } 2 ] 4 , have been prepared by the treatment of Ar*InBr 2 with Na[Co(CO) 4 ] and Na[Mn(CO) 5 ], respectively. The structure of 3 was established by single‐crystal X‐ray diffraction: space group P 1 (No. 2), Z = 2, a = 8.625(1) Å, b = 10.557(2) Å, c = 17.55(2) Å, α = 88.43(1)°, β = 83.45(1)°, γ = 71.14(1)°. The X‐ray crystal structure of [Ga{Mn(CO) 5 } 3 ] is also reported: space group Pbca (No. 61), Z = 8, a = 12.83(3) Å, b = 11.753(2) Å, c = 29.662(6) Å, α = β = γ = 90°.
