Synthesis and structures of three heterobiraetallic compounds based on a new ferrocenyl pyridine ligand

摘要

The reactions of 2-PAMF with metal perchlorates [2-PAMF = (2-pyridylmethylamino)carbo-nylferrocene] yielded three coordination compounds, M(2-PAMF)_2(CH_3CH_2OH)_2(ClO_4)_2 (M = Co 1, Zn 2, and Cu 3), which were characterized by single crystal X-ray diffraction and IR spectroscopy. Compounds 1 and 2 have similar structures with six-coordinate metals in octahedral geometries. The CuII in 3 possesses a severely distorted octahedral geometry due to Jahn-Teller distortion. Adjacent molecules in the three compounds were linked by intermolecular hydrogen bonds to form a 1-D supramolecular chain.
