Abstract
Zinc(II) halides form a series of of 1:1 and 1:2 compexes with neutral 2-pyridinecarboxylate esters, which act as bidentate nitrogenoxygen donors, via reaction in alcohol solution. Compounds of formula [ZnX 2(C 5H 4NCOOR) n ] with n = 1 (X = Cl, R = Me, Et, Pr 1 and X = Br, R = Et) and the whole series with n = 2 (x = Cl, Br, I and R = Me, Et, Pr i) have been obtained. The crystal structures of five complexes, [ZnX 2(C 5H 4NCOOPR i) 2] (X = Cl, Br or I) and [ZnX 2(C 5H 4NCOOMe) 2] (X = Br or I), have been determined. In all cases the structure consists of discrete neutral monomeric units where the zinc atom has a distorted octahedral coordination to two halides, in cis disposition, and to two 2-pyridinecarboxylate ester ligands by means of the pyridine nitrogen and the carbonyl oxygen atoms. The degree of distortion from regular octahedral geometry is compared to closely related structures.
