A μ-alkoxido-bridged tetranuclear oxidovanadium(IV) complex with 2,6-bis(hydroxymethyl)-4-methylphenol (H3bhmp), [Et3NH]2[(VO)4(Hbhmp)2(EtO)2(SO4)2] (1), was synthesized. The crystal structure was determined by the single-crystal X-ray diffraction method at 90 K. Compound 1 crystallizes in the triclinic space group P1 with a = 10.799(5)Å, b = 11.339(5)Å, c = 11.703(5)Å, α = 109.294(9)°, β = 114.158(7)°, γ = 102.452(9)°, V = 1127.0(8) Å3, Dx = 1.601 g/cm3, and Z = 1. The R1 [I > 2σ(I)] and wR2 (all data) values are 0.0548 and 0.1126, respectively. Compound 1 consists of triethylammonium cations and the di-μ-sulfato-di-μ-ethoxido-di-μ-alkoxido-di-μ-phenoxido-bridged tetranuclear oxidovanadium(IV) complex anion [(VO)4(Hbhmp)2(EtO)2(SO4)2]2− with a parallelogram array of four vanadium atoms.
