Preparation and X-ray crystal structure (for Ln = Sm) of (µ-phthalocyaninato)bis[di(2,2,6,6-tetramethylheptane-3,5-dionato)LnIII](Ln = Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, and Y)
Abstract
The reaction of dilithium phthalocyanine with tris(2,2,6,6-tetramethylheptane-3,5-dionato)LnIII(Ln = Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, and Y) affords a series of (µ-phthalocyaninato)(diketonato)4Ln2complexes; the X-ray crystal structure of the samarium compound shows that the phthalocyanine ligand bridges two samarium atoms each co-ordinated by two β-diketonato ligands, and important molecular parameters include Sm–Oav 2.284(17), Sm–Nav 2.656(16), and Sm–Smav 3.627(3)Å.
