Syntheses, structure and magnetism of a new linear-chain coordination polymer [[Co(TMA)₂(4,4′-bipyridine)₂] · H₂O]_n [TMA=Trimesate]

Abstract

A linear-chain one-dimension polymeric complex of Co(II), [[Co(TMA)₂(4,4′-bipyridine)₂] · H₂O] _n has been synthesized and characterized. The complex crystallizes in the monoclinic system, space group P2(1)/c with a = 11.344(3) Å, b = 15.880(4) Å, c = 23.436(5) Å, β = 117.831(10)°, V = 3733.5(16) ų and D _c = 1.437 g cm⁻³. The effective magnetic moment for this complex indicates that there is almost no ferromagnetic coupling between the Co(II) ions and the magnetic behavior is due to the isolated Co(II).
