Poly[(μ(2)-4,4′-bipyridine-κ(2) N:N′)bis­(μ(2)-2-phen­oxy­propionato-κ(2) O:O′)cobalt(II)]

In the polymeric title compound, [Co(C(9)H(9)O(3))(2)(C(10)H(8)N(2))](n), the Co(II) ion is located on a twofold rotation axis and is six-coordinated by two N atoms from two 4,4′-bipyridine (4,4′-bipy) ligands in axial positions and by four O atoms from four 2-phen­oxy­propionate (POPA) anions in equatorial positions, defining a slightly distorted octa­hedral geometry. The carboxyl­ate group of the POPA anion displays a bis-monodentate mode, linking pairs of Co(II) ions into a chain parallel to [001]. Adjacent chains are connected in a perpendicular manner through 4,4′-bipy ligands into layers parallel to (100). The 4,4′-bipy ligand is likewise located on a twofold rotation axis, with a dihedral angle between the two pyridine rings of 57.05 (7)°. C—H⋯O hydrogen-bonding inter­actions are present within the layers. π–π stacking inter­actions between the POPA benzene rings of neighbouring layers [centroid-to-centroid distance = 3.976 (3) Å and plane-to-plane distance = 3.618 (3) Å] stabilize the packing of the structure.
