      <subfield code="a">We describe a class of nilpotent Lie algebras completely determined by their associated weight graph. These algebras also present two important structural properties: to admit
naturally a symplectic form and to be isomorphic to the nilradical of a solvable complete rigid Lie algebra. These solvable algebras are proved to constitute a class of algebras where a symplectic form cannot exist. Finally we analyze the product by generators of the preceding
algebras, and show that this operator preserves the property of being the maximal nilpotent ideal of a solvable rigid Lie algebra</subfield>
