The cyclic vanadylacetate (C24H20P)[V4O8(C2H3O2)(4)(NO3)]

In the title complex, tetraphenylphosphonium mu(4)-nitrato-kappa(4)O-cyclo- tetrakis(mu-acetato-O:O')tetra-mu-oxo-tetrakis[oxovanadium(V)], the anion l ies about a twofold axis and consists of the cyclic [V4O8] unit coordinated by four acetato ligands with interatomic V ... V distances of 3.269 (1) an d 3.273 (1) Angstrom. The double-bonded O atom [N=O 1.102 (6) and N-O 1.268 (4) Angstrom] of the nitrate ligand links the four V atoms with V-O bond d istances of 2.613 (2) and 2.813 (2) Angstrom. The negative charge of the co mplex is balanced by tetraphenylphosphonium cations occupying the Na positi ons in the NaCl-type ionic packing of the structure.
