Description:
Abstract The title compound Me2Sn(NtBu)2GaMe (Me = CH3, tBu = C(CH3)3) is formed in only low yield by the reaction of diazadistannetidine [Me2SnNtBu]2 with galliumtrimethyl. It is dimeric in the solid state and crystallizes in the monoclinic space group P21/n with the cell parameters a = 923.4(1), b = 1832.8(2), c = 972.9(1) pm, β = 111.24(1)°, and Z = 2. The centrosymmetric dimer (point symmetry Q ) consists of three consecutive edge-sharing four-membered rings; the central Ga2N2 unit is formed by two Ga ← N donor-acceptor bonds of 203.7 pm. The two SnN2Ga rings and the central ring form angles of ± 113.7°. The compound is very similar to, but not isotypic with the homologous In/Si compound [Me2Si(NtBu)2InMe]2 [5],
