Two mixed‐metal‐center inorganic‐organic hybrid frameworks incorporating N‐(Phosphonomethyl)iminodiacetate(H 4 pmida), [Zn 2 V 2 O 2 (pmida) 2 (H 2 O) 10 ]·H 2 O ( 1 ) and [Zn 2 V 2 O 2 (pmida) 2 (H 2 O) 12 ]·2H 2 O ( 2 ), were synthesized by hydrothermal reactions and characterized by elemental analysis, IR spectra, UV‐Vis spectra and single crystal X‐ray analysis. In complex 1 , the centrosymmetric dimeric [V 2 O 2 (pmida) 2 ] 4– unit connected to neighboring Zn 2+ through the phosphonate group, while 2 the [V 2 O 2 (pmida) 2 ] 4– unit uncoordinated with the Zn 2+ in the presence of NaOH. Magnetic measurements in the range 2‐300 K have shown weak antiferromagnetic interaction between the adjacent vanadium ions in complexes.
