-tris(1,10-phenanthroline)ruthenium(II) in the dual-metal self-assembly of bis[tris(1,10-phenanthroline)ruthenium(II)] tetraisothiocyanatoiron(II) bis(perchlorate)Abstract: The title compound, [Ru(C12H8N2)3]2[Fe(NCS)4](ClO4)2, crystallizes in a tetragonal chiral space group (P41212) and the assigned absolute configuration of the optically active molecules was unequivocally confirmed. The -[RuII(phen)3]2+ complex cations (phen is 1,10-phenanthroline) interact along the 41 screw axis parallel to the c axis, with an Ru
Ru distance of 10.4170 (6) Å, and in the ab plane, with RuRu distances of 10.0920 (6) and 10.0938 (6) Å, defining a primitive cubic lattice. The Fe atom is situated on the twofold axis diagonal in the ab plane. The supramolecular architecture is supported by C-HO interactions between the [RuII(phen)3]2+ cation and the disordered perchlorate anion. This study adds to the relatively scarce knowledge about intermolecular interactions between [Ru(phen)3]2+ ions in the solid state, knowledge that eventually may also lead to a better understanding of the solution state interactions of this species; these are of immense interest because of the photochemical properties of these ions and their interactions with DNA.
Formula: [Ru(C12H8N2)3]2[Fe(NCS)4](ClO4)2
