On three-parametric Lie groups as quasi-Kaehler manifolds with Killing   Norden metric
  A 3-parametric family of 6-dimensional quasi-Kaehler manifolds with Norden metric is constructed on a Lie group. This family is characterized geometrically. The condition for such a 6-manifold to be isotropic Kaehler is given.
