<jats:title>Abstract</jats:title>
<jats:p>The title compound Me<jats:sub>2</jats:sub>Sn(N<jats:sup>t</jats:sup>Bu)<jats:sub>2</jats:sub>GaMe (Me = CH<jats:sub>3</jats:sub>, <jats:sup>t</jats:sup>Bu = C(CH<jats:sub>3</jats:sub>)<jats:sub>3</jats:sub>) is formed in only low yield by the reaction of diazadistannetidine [Me<jats:sub>2</jats:sub>SnN<jats:sup>t</jats:sup>Bu]<jats:sub>2</jats:sub> with galliumtrimethyl. It is dimeric in the solid state and crystallizes in the monoclinic space group P2<jats:sub>1</jats:sub>/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 Ga<jats:sub>2</jats:sub>N<jats:sub>2</jats:sub> unit is formed by two Ga ← N donor-acceptor bonds of 203.7 pm. The two SnN<jats:sub>2</jats:sub>Ga 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 [Me<jats:sub>2</jats:sub>Si(N<jats:sup>t</jats:sup>Bu)<jats:sub>2</jats:sub>InMe]<jats:sub>2</jats:sub> [5],</jats:p>
