资源简介：
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 (DM) interactions arising from
the polar noncentrosymmetric crystal structure. The ZnII compound exhibits a second harmonic generation (SHG) response of
approximately 0.2 times that of potassium dihydrogen phosphate (KDP).
