Abstract: Dimeric ammonium(glycollate)dioxovanadium (NH4)2[V2O4(OCH2COO)2]has been prepared.The complex crystallizes in triclinic space group P1 with unitcell parameters: a = 0.6124(1)nm, b= 0.6952 (1)nm, c= 0.8449 (1)nm, α=66.08 (1),β=64.21(1),γ= 78.01(1)°V=0.2958 nm3, Z=1, R=0.041.Thedimer contains a quasicentrosymmetric planar four-membered V2O2 ring with twoexocyclic glycollate entities coordinated by the oxygen atoms of hydroxy-and car-boxy late ligands.
