Crystal structure of poly[{μ3-(E)-3-[3-(carboxylatomethoxy)phenyl]acrylato-κ3O,O′:O′′:O′′′}[μ2-3-(pyridin-4-yl)-1H-pyrazole-κ2N:N′]cobalt(II)]

Abstract

The title compound, [Co(C11H8O5)(C8H7N3)]n, which is based on (E)-3-[3-(carboxymethoxy)phenyl]acrylic acid (H2L) and 3-(pyridin-4-yl)pyrazole (pp) ligands, has been synthesized under solvothermal conditions. The dihedral angle between pyrazole and pyridine rings in the pp ligands is 23.1 (2)°. In the crystal, helical chains formed by pp andLligands connected to the CoIIatom propagate parallel to thecaxis. CoIIatoms of adjacent chains are bridged by the acrylic acid groups ofLligands into corrugated polymeric sheets in theacplane.
