Resumen

The homoleptic Ga(III) amides [(t-Bu(H)N)₂Ga(μ-N(H)t-Bu)]₂ (1) and Ga(N(t-Bu)SiMe₃)₃ (2) have been synthesized via the reaction of GaCl₃ with 3 equiv of the appropriate lithium amide. A third tris(amide), Ga(tmp)₃ (3) (tmp = 2,2,6,6-tetramethylpiperidide), was prepared by the thermal reaction of GaCl₃ with 3 equiv of Htmp. The structures of 1 and Ga(N(SiMe₃)₂)₃ (4) have been determined by single-crystal X-ray diffraction methods. Compound 1 crystallizes in the monoclinic space group C2/m (No. 12) with a = 9.879(2) Å, b = 17.427(7) Å, c = 19.742(1) Å, β = 101.38(3)°, V = 3332(23) Å³, and Z = 4. Compound 4 crystallizes in the trigonal space group P31c (No. 163) with a = 16.050(1) Å, c = 8.6063(7) Å, V = 1920(5) Å³, and Z = 2. Compound 1 exists in the crystalline state as discrete dimeric units with two bridging and four terminal amido groups. The crystalline state of 4 comprises discrete monomers with D₃ symmetry. The structure of 2 is disordered.
