6-dimensional product Lie algebras admitting integrable complex   structures
  We classify the 6-dimensional Lie algebras of the form $g\times g$ that admit integrable complex structure. We also endow a Lie algebra of the kind $o(n)\oplus o(n)$ with such a complex structure. The motivation comes from geometric structures \'a la Sasaki on $g$-manifolds.
