We prove that any zero torsion linear map on a nonsolvable real Lie algebra 𝔀 0 is an extension of some CR-structure. We then study the cases of 𝔰 𝔩 (2, ℝ ) and the 3-dimensional Heisenberg Lie algebra 𝔫 . In both cases, we compute up to equivalence all zero torsion linear maps on 𝔀 0 , and deduce an explicit description of the equivalence classes of integrable complex structures on 𝔀 0 Γ— 𝔀 0 .
