|Abstract:||Two one-dimensional coordination polymeric chains namely, [Zn7(μ4-O)2(CH3CO 2)10(bpe)] (1) and ([Zn7(μ4-O)2(CH3CO 2)10(dpds)] (2) (bpe=1,2-bis(4-pyridyl)ethane and dpds=4,4′-dipyridyldisulfide) have been obtained by self assembly method from Zn(O2CCH3)2 and spacer ligands dpe and dpds in the ratio 7:1, and characterized by X-ray crystallography. Compound 1 is a quasi-linear one-dimensional coordination polymer whereas 2 has the zigzag polymeric chain structure. The conformations of the backbone of these flexible angular ligands appear to influence the way in which the heptanuclear metal aggregates are bonded in the solid state. In 1, the py-C-C-py fragment has an anti conformation with the torsion angle, 180°. The S-C-C-S torsion angle for dpds in 2 is 61.8(5)° with the interplanar angle between the pyridine rings of 89.4(4)°. © 2002 Elsevier Science B.V. All rights reserved.|
