Cation-Induced Dimerization of Crown-Substituted Phthalocyanines by Complexation with Rubidium Nicotinate As Revealed by X-ray Structural Data
The supramolecular dimeric complex [(mu-oxo)bis(tetra-15-crown-5-phthalocyaninato)(nicotinato)- aluminum(III)]tetra(rubidium) bis(nicotinate) was prepared by addition of an excess of a methanol solution of rubidium nicotinate to a chloroform solution of the aluminum crownphthalocyaninate, [(HO)Al(15C5)(4)Pc]. A single-crystal X-ray diffraction study of {[Rb-4(NicAl(15C5)(4)Pc)(2)(mu-O)](2+)(Nic(-))(2)}center dot 2.36HNic center dot 11H(2)O demonstrated that two molecules of the aluminum crown-phthalocyaninate nicotinate are connected through an Al-O-Al bridge supported by sandwiching of crown ether moieties by Rb+ cations.
