Coordination of Piano‐Stool Complexes to a Hydrogen‐Bonded Rosette‐Type Assembly

A new melamine (ME)–barbituric acid (BA) rosette‐type system has been prepared and characterized. The introduction of a pyridyl group on the barbituric acid moiety allows coordination of metal ions at the periphery of the MEBA rosette. Reactions of 1.5 equiv. of [Ru(cym)Cl] (cym = ‐cymene) or [M(Cp*... Full description

description: A new melamine (ME)–barbituric acid (BA) rosette‐type system has been prepared and characterized. The introduction of a pyridyl group on the barbituric acid moiety allows coordination of metal ions at the periphery of the MEBA rosette. Reactions of 1.5 equiv. of [Ru(cym)Cl] (cym = ‐cymene) or [M(Cp*)Cl] (Cp* = pentamethylcyclopentadienyl; M = Rh, Ir) with the rosette afford the corresponding ME[BA{Ru(cym)Cl}] and ME[BA{M(Cp*)Cl}] assemblies. The neutral metal‐containing rosettes ME[BA{Ru(cym)Cl}] and ME[BA{Rh(Cp*)Cl}] can also be obtained by adding the mononuclear complexes [BA{Ru(cym)Cl}] and [BA{Rh(Cp*)Cl}] to ,‐bis(4‐‐butylphenyl)melamine in chloroform. In addition, the triphenylphosphine derivatives [Ru(cym)(PPh)Cl] or [M(Cp*)(PPh)Cl] react with MEBA in the presence of silver triflate to generate the ionic rosette‐type assemblies ME[BA{Ru(cym)(PPh)Cl}]3CFSO and ME[BA{M(Cp*)(PPh)Cl}]3CFSO, respectively. Rosette‐type assemblies mixing covalent, coordination, hydrogen‐bond, and ionic interactions have been synthesized and characterized, providing a new strategy for the preparation of metal‐containing supramolecular assemblies.
