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)]

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 and L ligands connected to the CoII atom propagate parallel to the c axis. CoII atoms of adjacent chains are bridged by the acrylic acid groups of L ligands into corrugated polymeric sheets in the ac plane
