In this paper, the frames of spaces of complex $n$-dimensional Lie algebras (that is, the intersections of all irreducible components of these spaces) are studied. A complete description of the frames and their projectivizations for $n\le 6$ is given. It is also proved that for $n\le 6$ the projectivizations of these spaces are simply connected. Bibliography: 7 titles.
Keywords: Lie algebra, irreducible component, nilpotent Lie algebra, contraction.
