Summary
A variety of metal(II) complexes of 2-carbethoxypyridine (L) have been prepared and characterised. With metal(II) chlorides the bis complexes can be formulated [ML2Cl2]o (M=CuII, NiII, CoII, FeII or MnII). The complexes are six-coordinate with 2-carbethoxypyridine acting as a bidentate ligandvia the pyridine nitrogen and the carbonyl group of the ester. The chloro complexes are nonelectrolytes in nitroethane; magnetic susceptibility measurements, i.r. and d-d electronic spectra are reported. With metal(II) perchlorate salts the complexes can be formulated as six-coordinate [ML2 (OH2)2] [ClO4]2 species containing ionic perchlorate. The ester exchanges of some of these complexes with a variety of primary alcohols have been investigated.
