چکیده
In the title compound, C(26)H(20)N(6)O(4), the two aroylhydrazone side groups exist as diastereomeres, both in the keto form in the crystal structure. The aroylhydrazone units support the mol-ecular conformation through an intra-molecular N-H⋯O hydrogen bond. Two mol-ecules are connected into a centrosymmetric dimer by inter-molecular N-H⋯N hydrogen bonds. These dimers are connected into chains along the a axis by inter-molecular O-H⋯O hydrogen bonds. The combination of these hydrogen bonds results in layers in the bc plane. The layers are further linked by weak C-H⋯π contacts to form a three-dimensional network structure.

In the title compound, [Ru(C(10)H(8)N(2))(2)(C(21)H(18)N(4)O(4))](PF(6))(2), the Ru(II) complex cation reveals a slightly distorted octa-hedral coordination. The coordination bonds of the 4,4'-substituted bipyridyl donors [Ru-N = 2.038 (3) and 2.051 (3) Å] are shorter than those of the 2,2'-bipyridyl donors [Ru-N1 = 2.065 (3)-2.077 (3) Å], due to the electron-withdrawing effects of the substitu...
