The hydrothermal reactions of 4-[(phosphonomethylamino)methyl]benzoic acid (H3L) with M(NO3)2 (M = Co, Zn) afford two metal phosphonates, namely, Co(HL) and Zn(HL). Both of them display a 3D polar pillared layered structure. Magnetic measurements confirm that Co(HL) exhibits a canted antiferromagnetic ordering at about 2 K. A weak ferromagnetic component at low temperature is attributed to the Dzyaloshinskii–Moriya
