The hydrothermal reaction of glyphosate and Co(Ac) 2 ·4H 2 O in the presence of water and ethanol at different temperatures affords two novel cobalt coordination polymers: C 12 H 30 N 4 O 20 P 4 Co ( 1 ) and C 3 H 10 NO 7 P 1 Co ( 2 ). Both structures were determined by single crystal X‐ray diffraction. The coordination polymer of 1 is a one‐dimensional chain polymer with the crystal data: $\rm P{\bar 1}$ , a = 5.5010(7), b = 10.983(2), c = 11.381(2) Å, α = 69.848(2), β = 86.645(2)°, γ = 79.788(2), V = 634.6(2) Å 3 , Z = 1, R1 = 0.0548, wR2 = 0.1557, whereas the coordination polymer of 2 is a two‐dimensional layered polymer with the crystal data: $\rm P{\bar 1}$ , a = 8.9669(7), b = 7.3670(5), c = 12.7577(9) Å, β = 101.433(2)°, V = 826.04(10) Å 3 Z = 4, R1 = 0.0325, wR2 = 0.1125. The glyphosate ligand exhibits different coordination behaviors in these two coordination polymers. Research on magnetic behavior revealed an antiferromagnetic coupling interaction between the Co 2+ ions in both compounds.
